Except when they try to talk about men's issues, feminists protest them. It's one of the first shots in the documentary for god's sakes- they're having a rally about men's issues and feminist protestors are shouting them down even though what they're talking about has nothing to do with feminism. A number of MRAs both male and female started off as feminists and the moment they made the radical next step to say "hey, men have issues as well- maybe we should address those also" they were virtually excommunicated by feminists- most dramatically in the case of Erin Pizzey who had to flee Britain because of the amount of DEATH THREATS she was receiving from feminists because of the radical belief that women are capable of being abusers as well- not just men.
As she said about the first shelter she ever set up "I bought the bloody building but I can't even set foot in the door because the woman, the feminist who owns the place despises me"
How is anyone supposed to advocate for their cause when they're not allowed to speak?
It looks like they were allowed to speak, but that is beside the point. I do not know the circumstances of that rally, but I suspect that it being linked with RedPill is what drew so many protesters (or counter-protesters). Like I said, MRA's have a very bad reputation. What they need is an advocacy organization focused purely on advocacy that does not tolerate hate. As that organization builds a reputation, they may be able to shift perception.
That will not change the attitudes of radicial feminists of course; however, I do not view that as an excuse. Transgender people are extremely hated by radical feminists, to the point we have an acronym for them, TERFs (trans-exclusionary radical feminist). Every trans person knows this acronym and is afraid of being doxxed and harassed by terfs (they do more than death threats to us). We also have a lot of hate in our community and many people to hate (the Republican Party, some LGB organizations that have moved to 'drop the T', everything supportive of cisnormativity in general); however, we do not let that into our advocacy organizations. The National Center for Transgender Equality is not drawn from the hateful recesses of angry bitter trans forums.
The MRA movement has far more people, so why aren't they properly organized? I mean, this looks promising (at least on the surface anyway):
http://www.nationalcenterformen.org/ So why wasn't the documentary given a title associating it with this instead of with the Red Pill? It would be like if someone made a trans advocacy documentary something like "Tumblr Speaks: Die Cis Scum". You cannot let dumbasses on the internet define your movement or everyone will hate you and you wont get anywhere. The RedPill is reddit, and reddit is a cesspool.
I get why sexism is bad, but what's wrong with wanting to get laid more?
Because the attitudes that go with it on RedPill generally display a lack of respect for woman as human beings. Take their recent popular thread on Aziz Ansari for instance. They go on and on about how he didn't force her, yada yada. They do not empathize with her or how awful it was for her to be ignored when she says she wants to leave (a.k.a. a deescalation tactic) and have her path to the door blocked
repeatedly by Ansari. The whole point of the #metoo movement is to try to get men to empathize with women so that they discontinue this behavior, not to ruin careers or toss everyone in jail. But it is failing miserably in this regard, especially on RedPill. Do you think guys on Redpill advertise the fact to women they want to date? No, and women are generally unhappy to learn that their boyfriend goes on RedPill. These attitudes fuel rape culture (which they would probably fail to acknowledge the existence of).
It should be possible to simultaneously be a MRA and a feminist, but it will only work if people can step back from the bombardment of internet hatred. I know it is difficult, but trans people are doing it. If we can, anyone can (because we have such an incredible amount of hatred aimed at us).
