I'm cis, so it's not my place to make this call, but there's a situation (outside of social media) where a trans man with whom I am only passingly acquainted has decided that it's somehow 'phobic to have a cishet white woman (for the record, this woman is the archetypal PFLAG mom who's done more for the queer community this month than you or I will do all year) acting as a media flack for Pride -- and he is on the warpath about it, and anyone who criticizes his clearly abusive behaviour gets loudly called transphobic.
So the question is, how do you tell a trans man to go fuck himself without non-clued-in outside observers thinking it has anything whatsoever to do with his gender status, which at the moment is literally the only aspect of his being I *don't* have a problem with.
