I can’t believe people here are saying what they do in the privacy of their bedrooms are no concern to us! If only that were the case! Everything you cite is the exact opposite of privacy.
And for gay men, sexuality, the penis, is the only thing they think about. They are sexual obsessives. Even a genius, like the late great Quentin Crisp (who I was privileged to know) admitted this. He was pilloried for it.
In contrast, having the US transformed to a Third World country through mass immigration does effect my quality of life, as does the proliferation of radical jihadi movements and radicalized racial movements like BlackLivesMatter. That's why I really have no objection to someone like Milo Y. being treated as a political ally. It's also the reason why even people who find homosexuality disgusting found the jihadi attack on homosexuals in Orlando infinitely more disgusting.
It's a matter of picking your political fights.
