For example, I didn't know anything about Scientology for a long time, and only recently learned about their abusive behaviour and crazy beliefs. I'm glad I never supported Scientologists, even if they say they're being unfairly persecuted.
I get homosexuality and support LGB rights. Pansexuality just seems like bisexuality with some navel gazing added so whatever.
Asexuality has no reason to concern anyone, though I think it may often be the result of social issues, like the effect porn has on people, rather than an actual orientation, so I think it's ok to scrutinize as a concept and collectively think about more. I could say more but the post will get way too long.
Trans/NB/genderqueer/etc. make no sense to me. I'm still waiting for someone to explain how one can say "trans women are women" without redefining "woman" on the basis of sexist stereotypes or turning it into a vacuous definition without any meaning whatsoever, both of which are unacceptable and lead to serious real life issues that we can already observe. The transgender movement needs an internal revolution before I'll support it.
