Yes, as far as I can follow this, 'genital preferences' are transphobic, and people should work hard to overcome them. Lots of examples in this article. medium.com/@rogerdubar/no-your-sexual-preferences-are-not-transphobic-8808b8ec2cd0
I think this is the position. It makes no sense to me and I don't understand how it hasn't been firmly knocked back by all concerned, but here we are. Gender identity trumps sexual orientation. Biological sex is irrelevant until someone wants a baby, when miraculously they all know exactly whose services are needed.
Male human, sexually attracted to female humans, identifies as a male = straight or heterosexual man.
Same person, now identifies as a woman = lesbian. Women, i.e. female humans, who are only sexually attracted to other women are now expected to include this male in their dating pool. They are told they can get used to male genitalia if they just work at it. Sickening and very obviously homophobic against lesbians.
___
Female human, sexually attracted to female humans, identifies as a female = lesbian.
Same person, now identifies as a man = straight man. Does this make any lesbian who has a relationship with this person a straight woman?
Male human, sexually attracted to male humans, identifies as a male = gay man.
Same person, now identifies as a woman = straight woman. As above, does this make gay men who have sex with this person into straight men?
_
Female human, sexually attracted to male humans, identifies as a female = straight woman.
Same person, now identifies as a man = gay man. Expects to be included in the dating pool of gay men. As you might expect, gay men are proving very resistant to this idea, and are getting far less grief for their stance than lesbians in the equivalent position. Obviously, gay men are not at much risk of violence from trans men, whereas lesbians unfortunately are at risk from trans women, as from all other males.
