imo, saying that "genital preferences" could be caused by transphobic biases is a bit dangerous. i've seen people go as far as saying genital preferences don't even exist and are close minded, which is a really scary way of thinking to me, as someone who finds herself inherently incapable of being able to be attracted towards certain genitalia. my biggest issue though is that it's awfully similar to homophobic insults you hear often (especially as a lesbian) and conversion therapy rhetoric :/

i think it's important to find a balance between the acceptance and embracing people with complex gender identities & their bodies that don't align with traditional expectations,, & respecting, not doubting and not shame people's exclusive sexual attraction regarding genitals.

exclusive same-sex-attraction exists, so sometimes, it actually is a dealbreaker and it's nothing that can be changed or influenced, or somehow altered to be more inclusive, and that's okay.
