I have seen various people on this forum say that to be gay or a lesbian is to be ‘exclusively same sex attracted’, and that therefore, for example, a woman who is attracted to or in a relationship with a trans woman cannot correctly describe herself as a lesbian.
Setting aside the problems with presuming to correct another person’s understanding of their own identity, I can’t see how this absolutist approach is logically sustainable. If I am a non-trans woman who has only ever - to my knowledge - been attracted to other non-trans women, but then am attracted to and get off with a woman in a bar who I subsequently find out is trans, do I immediately stop being a lesbian? What if I don’t stop finding the trans woman attractive after learning that she’s trans? What if I never find out she was trans - is it the case that I have ceased being a lesbian, but will never know this?
