Honestly I think the thing that bugs me the most about the “STRAIGHT PEOPLE HAVE A PLACE IN LGBT BECAUSE STRAIGHT TRANS PEOPLE” thing is like:

We have a hard enough time getting straight trans men OUT of lesbian spaces, straight trans women have the “really just gay men” stereotype, and unless it’s a lesbian-only space, there’s really no way to kick out a straight trans women out of an LGBT space that isn’t routed in transmisogyny.

If anything “straights aren’t allowed in LGBT spaces” gets directed at trans lesbians and gay men more than it does trans people who are actually straight.
