These lists aren't about homosexuality (or communism or adulterers or whatever), it's about attacking ideological and political opposition. The list makers never include "transgressions" of people aligned with them on their lists. If they can bully and intimidate their opponents about their sexuality they'll do that, if not they'll find something else. That's how these things work.
So it’s not because they are gay, it’s their behaviour.
I am glad we finally agreed though I am sad we had to spend as many steps to reach this conclusion.
