I'd say that the underlying phenomenon is classic xenophobia. These are just specific cases of it, where the "foreign/different/alien" thing is someone's sexual or gender preference, or even opinion on the validity of those things. (EG it's possible for a homosexual to be anti-homosexuality: their tribal affiliation's homophobia is stronger than their personal sexual orientation. Then you get headlines about a "Wide Stance".)
