OOhhhhh, nice topic! It isn't about specific ideas, because those specific things aren't enough if I'm in cooperation with someone in some way, because I can always talk with them and reason with them. Anybody has views and attitudes that came from somewhere, and so it's a matter of speaking to that. I'm pretty good softly making them realize that there are things missing from their perspective.
But there are times when hatred just consumes me. I don't exploed, I just don't, and it hasn't happend, but I have developed grudge-like hatred. So, I have a friend who I'm close to who is a hilarious guy and a really cool person, but some people just don't get him, and while some will just be reasonable and accept that there is a weird but yet good-willed character in front of them, others have made the mistake of disrespecting him in an overt way... Just thinking about it makes me feel like I'm on fire with defensiveness..... I haven't stopped hating the few people who would disrespect someone as nice and good-willed as my friend...
So really, there isn't a viewpoint or an idea that lights me on fire with defensiveness, because eyes and perspectives can be adjusted. What gets me are those occasions where people can actually take the steps in a motivated way to really disrespect someone with the clear message of tearing them down, maybe make them more downtrodden than they already were... That fills me with sooooo much anger and hatred, and I won't likely forgive them.
