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.
> After all, if they are being bullied because they are gay, all gay people should be listed on there.
I don't know what you mean. That's not a gotcha.
