i think people need to understand that for a lot of trans people (including myself) no relationship we have with someone is gonna be “straight”. all of my relationships no matter who they are with will be queer in some sense. for trans guys attracted to women or even just attraction that does not include cis men is often adjacent to the history of their sexuality either as a lesbian or queer woman. it is in the end just someone’s own personal connection to the label of lesbian.
I am a lesbian, and I think (and its fully a personal thing) feels like it’s not a space for non men anymore. It’s already hard to have no men spaces, and having a sexuality that is no men, but men try to come in makes me feel uncomfortable? At the same time though I don’t think I will ever meet a trans man who says they are a lesbian
