Sometimes they must necessarily be excluded. You just referred to trans people without referring to bi people. Were you "excluding" bi people? Well, in the sense of the word that you just (perhaps unintentionally) used, yes, you just excluded them. And it was okay. Because you weren't talking about bi people. So it was okay to say "trans" instead of "2SLGBTQ+". Because you were speaking specifically about trans people and that is OKAY. So what would you have me say when I am specifically talking about lesbian, gay, and bisexual people but not trans people??!!

You're so hung up on dogma and culture warring that you're not using your brain.
