I think it’s interesting that, in multiple things I’ve read, gays & lesbians are not in board with the trans thing.
True.
There is actually a lot of hidden animosity between the alphabet letters, hidden to project a false picture of solidarity. The "B's" are often considered "impure" members of the acronym, since they can still settle down with an opposite sex partner or be exclusive with the opposite sex (the nerve!) Lesbian and "gay" bars are often segregated, for obvious reasons. A growing disdain for trannies is also apparent. The official "news" doesn't match the reality.
