Yeah, I've seen this with some people I know too. Though sometimes I show this to one of my gay friends and he just brushes things off as being exceptions, isolated cases, etc.

A big issue I see is that people often claim that we're using the false equivalence fallacy. I mean, if you see a gay guy supporting "heterophobia" it is a false equivalence to say it's the same as straight people supporting homophobia. Their logic is that it's the same when trans people are homophobic. That one friend is like that, he only complains about homophobia when it comes from conservative cis white men, otherwise he'll brush it off as being that gay guys are less oppressed than other groups so it's a false equivalence to criticize homophobia from these groups.

Not that I disagree with you. I think showing examples of what is going on is the best shot at making people start support gay men/lesbian women more, instead of supporting views that are inherently homophobic. Yet, changing is always hard for people, and many people prefer to ignore something even when they see it. It might be our best shot but it isn't easy.

Honestly the current situation makes me feel pretty lonely when I'm trying to make friends, or when I talk with people who are already my friends/acquaintances. I might be talking about the representation of gay/lesbian characters in media with a gay friend and he just has to say something like "oh but what about trans representation" (and he is more moderated then the guy I mentioned above!). It's pretty lame when you find out the other person supports these views.
