"Actually, a considerable number of trans ideologists share the objectively homophobic belief that exclusive same sex attraction is bigoted, and that lesbians have no rights to organise for themselves without males. No "can be portrayed as" or "bit of spin" needed. Here are some examples."
Believing that certain people are 'naturally capable' of enjoying relationships/sex of particular kinds, but prejudice/bigotry/social conditioning etc gets in the way, is only "phobia" if you do not share the belief.
If Riley, as one example on your link, had suggested that there are people out there who are 'naturally capable' of relationships/sex with members of the same sex but prejudice/social conditioning gets in the way, no-one would call her heterophobic. Because then they would agree.
I mean we know that this sort of thing happens. Well, maybe not quite so much nowadays as historically , but you can stil get people to this day for hom this applies. People who are naturally bi/homosexual but 'in the closet'. And saying that is not heterophobic.
Anyway, my point still stands that 'some people who are trans say X' is not the same as 'transgendrism says X'.
