Okay, had lunch, helped my parents with some housework, took the dog for a walk, did some laundry, and I have 2 hours until D&D night with an INFP, an INFJ, an INTJ, and two people of unknown MBTIs. Back to this.
Let's review the standard taxonomy of sexualities, as was explained to me by a fairly authoritative website on the subject. You have pansexuals, who are attracted to all gender categories. You have bisexuals, who are attracted to at least two gender categories. And you have monosexuals, who are attracted to one gender category.
Monosexuals are usually divided into hetero- and homosexuals. That's somewhat problematic in general, since it marks out homosexuals as a minority. Whether that's a problem or not depends on what you're trying to do. It could be helpful to mark out homosexuals as a minority if you're wanting to create pan-queer solidarity. But lumping people who like women and people who like men together might help make society less heteronormative and more inclusive. At any rate, in this discussion, it's the gender of the person doing the attracting and not the gender of the person being attracted that's the topic, so "homo-" and "heterosexual" would be very clunky terms to use for this discussion. Let's talk instead about femisexuals and virisexuals instead, and temporarily define those terms as "people who are attracted to women" and "people who are attracted to men." I'll propose modifications to those initial definitions as we go.
(Ugh. "Doing the attracted," "being attracted." Implies that the attractive person is the one taking action, and the person being attracted is the passive one. In reality, being attracted is, if not an action, then at least a disposition towards action, and being attractive is not even that. But I can't think of a better way to phrase it off the top of my head.)
Another problem with this taxonomy is that "-sexual" seems to imply that we are attracted to sexes, not genders. But the asexual and aromantic communities have also adopted this phrasing, and it is useful to distinguish between sexual and romantic attraction. So I think we're stuck with it.
'Bisexual' is problematic, because it was coined at a time that many/most people thought there were only two genders. 'Plurisexual' might be a better way of putting it, if we want to capture "attracted to at least two genders, might or might not be pansexual." So let's temporarily define 'plurisexual' as somebody who is attracted to both men and women.
Now we actually need to take a closer look at what we mean by "x is attracted to y," or "y's are attractive to xs." When somebody says "I'm attracted to women," it is highly unlikely that they mean they are or would be attracted or to
every woman in the world, and every possible woman that could ever exist. A better option for translating this sentence is with generic quantification. When philosophers, logicians, and some mathematicians quantify things, we use explicit adjectives like 'all,' 'some' (at least one), or 'none.' But when humans in general say sentences of the form "Xs are Y," we generally mean something subtly different.
According to the theory, generic quantification has several criteria, and if any one of those criteria are satisfied, then the generic quantification is held to be true. The problem is that once we have accepted a generic quantification as true, we humans are likely to conclude that the other criteria are also satisfied, when, in reality, they are not.
For example, only a very small minority, less than 1% of sharks, have the dangerous property of eating humans. Because man-eating is such a dangerous property, a lot of humans accept the generic quantification "sharks eat people" as true. This is despite the fact that only a small minority of sharks have this property, and none have that property "naturally" -- sharks only bite a limb off people when they confuse us for seals, and are disappointed because we don't have much blubber. ("Hey, where's the cream filling?") But they've already bitten it off, and it's physically impossible for them to spit it out, so they have to swallow the limb, and then swim off, leaving a survivor to tell the tale. But because "sharks eat people," a lot of people want to kill all sharks on sight.
In the context of sexuality and object gender, the criteria for generic quantification that is probably most relevant goes something like "Xs are Y" is true if there is a subset of X that has Y, in either the sense that a majority of that subset of has Y or that subset as a whole has Y as a "natural" property, and there is no other subset within an alternative property that is psychologically positive in either of those two senses of 'has.'
"Psychologically positive" roughly means "noticeable to humans," while "psychologically negative" roughly means not immediately noticeable. The classic example of a psychologically negative trait is "the curious thing the dog did at midnight," i.e., not bark at the intruder (because the dog knew who the intruder was). A dog barking at midnight is psychologically positive, a dog not barking at midnight is psychologically negative.
You being attracted to somebody or repulsed by them are psychologically positive traits that the person 'has,' relative to you. You being merely indifferent towards somebody is a psychologically negative trait that the person 'has,' relative to you.
Being repulsed is psychologically positive, even 'dangerous,' but I think being actively repulsed by someone sexually could indicate that part of your brain actually
is attracted to them, but the rest of your brain is shouting "No!!!!!" The "latent homo- or bisexuality" theory of homophobia. For the rest of this discussion, I'll assume that nobody is strongly repulsed by anybody else, and the farthest our sexual disinterest in any other adult human goes is "indifference." If you are actively repulsed by someone sexually, you might want to talk to your therapist about it
If a femisexual does not find trans women attractive, that is not strong evidence that the femisexual is not attracted to women or that trans women lack a feminine object gender. That's because indifference is not a psychologically positive trait that the trans women 'have,' relative to the single femisexual.
And there are pragmatic reasons why we shouldn't think people aren't "real" women if they aren't attractive to a given femisexual. It would be a logically self-consistent position to take, but... um. Okay, if you want to be the one to tell a person who identifies as a woman, who has two X-chromosomes, a vagina, enlarged mammaries, but, uh, how do I put this delicately? a "butter face," that she isn't a "real" woman because you, personally, aren't attracted to her, well... It's a free country, but could you let me loan her my stun-pen and pepper-spray first? I want to watch, and possibly provide her with some back-up. She might need some help and eye-witnesses if she wants to Cancel you in response to your act of Free Speech.
A femisexual being attracted to a trans man is more disruptive to our taxonomy, since being attractive is a psychologically positive trait the trans man 'has,' relative to the femisexual, and because, so far, we are assuming that femisexuality is a subset of monosexuality. Being attracted to both women in general and at least one trans man (who is not a woman, but a man) is proof positive that you are attracted to more than one gender.
If we operate according to the standard taxonomy of sexualities, being attracted to women and at least one trans man would place you in the category of "bisexual," since you are attracted to people from at least two genders. I fall into this category, but I'm not exactly in a hurry to submit my application to the Bisexual Cabal, and I'm not sure how willing they would be to accept my application on these grounds. I think accepting that I'm bisexual and requiring "other" bisexuals to accept that I'm one of them would be a better alternative than me insisting on misgendering trans men I happen to be attracted to. But it's still not an attractive option.
What I suggest we do instead is to redefine what we mean by "femisexual," "virisexual," and "bi-" or "plurisexual," and throw out our concept of "monosexual" entirely.
What we could do is redefine "femisexual" to use 'femme' not to exclusively mean 'woman,' but in a more expanded way that at least one queer activist uses 'femme.' The way that activist uses 'femme' is centered on cis women, but it only excludes cishet men. She expliciltly intended it to include gay men, gender non-binary, gender-fluid, and both (main) categories of trans folk. Given, um, certain terms gay men use to refer to each other, and which I do not have the privileges to use myself, I think gay (cis) men might be okay with using 'femme' in this extended sense, but, um, cis men in general are not objects of attraction for this particular femisexual. I'm not sure how trans men would feel about it. But there is a certain blunt honesty about it, since when a femisexual is attracted to a trans man, it is likely that at least some of what is attracting us is his remaining feminine traits.
Same thing with the "vir-" in "virisexual." Centered on cis men, but excluding only cis women. Again, not sure how well a trans woman would take to being described as "virile," but there's still that same blunt honesty at work.
[ETA: And we could adjust our definition of "bi-" or "plurisexual" to means somebody who is attracted to at least cis men and women. That would mean that it would still be an open question of whether a plurisexual person is also a pansexual, just as it was with the original taxonomy.]
I'm not sure how well this alternative measures up relative to me coming out as "bisexual," since I'm not the only one whose needs matter. But acknowledging that object gender might not always line up with agent and social gender might be important when it comes to convincing society to accept trans people.
A limit on propaganda is that it cannot contradict the audience's lived experience. Philosophical argumentation is a form of propaganda that aims at also at getting at the truth. A political slogan might be true, but if it runs counter to the audience's lived experience, they are still not going to accept it unless you can explain the apparent contradiction.
When trans advocates say "trans men are men, trans women are women," I think what they are saying is "social gender should be brought into alignment with agent gender." But I'm afraid what a lot of the audience, particularly cishet men like myself, hear when somebody says "trans women are women" is "if you're a femisexual, then you should be attracted to trans women." That second interpretation runs counter to the lived experience of at least one, possibly three, probably most cishet men, so I'm afraid that if cishet mean interpret that slogan in that way, they are going to reject it. And something similar holds for cishet women and "trans men are men." But that's as not as politically important, since women's sexuality still doesn't carry as much weight as men's sexuality.
Okay, that's a good breaking point. So I'm going to post it and see if it gets me Cancelled. If it doesn't, I still have a few things to say about how trans folks themselves are painfully aware that their object gender might not always align with their agent gender, and the implications the fact that object gender is sensitive to medical intervention might have in long-term relationships.
