Preference implies that there're options in the first place, and TRAs (just like religious fundamentalists) use this to undermine the immutability of homosexuality. Which also pushes the idea that homosexuality is a voluntarily chosen identity, and only bigotry (transphobia) keeps us from changing ourselves. Identity is something you can critically examine and challenge, so of course it's in the TRA's best interest to push this new narrative. Don't fall for it. You give them this small change of our definitions and next thing you know they compare the sexual preference for blond hair to our sexual orientation. If you're homosexual, opposite attraction simply isn't an option. What do you "prefer" about your homosexual attraction, and what exactly do you prefer it over? And what does it have to do with you BEING homosexual? I we're talking about the objective state of my existence, then I don't 'prefer' to be a man, I AM a man. I AM gay. Being something and preferring something are two different things, they're not synonymous.
