Ah true. But even if she's not you know what I mean, she's in the "real lesbians aren't attracted to trans women". The actual concern this woman has is that lesbians within the lgbt community are embracing transwomen and when they do that, they stop being lesbians in this person's eyes. Thus lesbians disappearing is what they think is occurring.

She probably gets icky feelings if another woman she wants to date has ever been with a trans woman. Like they're impure or something. Have seen similar behaviour from racists. It's also like "virginity" in a way.
