Moderation is always going to be a tricky game. People assume that any comments that aren’t deleted are therefore validated by mods, even when they can cover extremes that are very far apart. With a topic like this, the extreme ends are probably going to be people at one end who think anyone who doesn’t confirm to a ‘traditional’ sexuality is some kind of abomination, and at the other end folk who think the people saying the ‘abomination’ shit shouldn’t be allowed to participate. It’s gonna be very hard to moderate that without pissing at least some people off. Like I say, a tricky game - but just because some people are unhappy doesn’t mean you’re doing it wrong.
Me, I’d say that unfortunately there are some extreme opinions out in the world and even when I don’t share them I don’t want to pretend they don’t exist. I’d rather have the opportunity to discuss them, dispute them, maybe try to change them. But open hate speech, threats, personal abuse, or advocacy of violence should be a definite no. Just IMO.
