I get the impression that they have some sort of subconscious self-hatred going on. After all, they're here, and they've indicated they've played the game in some of their responses.. But they advocate for changing the game to make it 'less mean' toward LGBTQ+ people.
This leads me to suspect that they subconsciously feel ashamed of themselves for having enjoyed this content in the past, and have seen bad actors use content like this to persecute LGBTQ+ people.. And that's led them to conclude that this sort of content is what's causing people to not support LGBTQ+ people's rights.
The problem with that is that they're giving credibility to the source of that hatred. Bigots that are against LGBTQ+ rights won't be okay with letting a 'non-perverted' version of the LGBTQ+ community exist, because to those bigots the very definition of every form of the LGBTQ+ movement is perverted. Trying to tame the LGBTQ+ movement and make it 'less perverted' is not going to appease the bigots, and is only going to weaken the entire LGBTQ+ movement.
I've hopefully at least started to convince them of this (as they've not responded to any of my posts for a few days now, while previously they responded every day), but it could also be they've simply been trolling and doing exactly what I described to them (about bigots posing as LGBTQ+ people and sowing seeds of in-fighting by trying to rally other LGBTQ+ people against the 'more perverted' LGBTQ+ people).. And when they realized they couldn't actually refute the arguments I presented without making that more obvious, decided to quit before they got further behind.
I hope that's not the case, and that it's just that they have some subconscious self-hate and shame that was planted in them by such trolls, and are now realizing what they've been doing and are quitting before they make things worse while they think things over.
Or it could be that they have a good guess about which other communities I'm in that I mentioned vaguely, and that made them uncomfortable with chatting with me. Which is honestly understandable, though a little sad.
