Know your own powerlessness.
I think it has to do with the topic's controversy (sadly lol), so it's assumed that trolls would be more prominent than they would be in any other PS chat, that's why I feel they're opposed to it. Although, I think a Discord one would be nice, it's much easier to moderate in case any troll shows up and stuff. Also, I'm sure there will be a lot of topics to talk about, given that it is a more casual enviroment than in a forum, which also involves dynamism and such :PI mean..I don't see why we should hide? If there's a Japanese, Sports, Chess, Health and Fitness chat, why not an LGBT one? It isn't the point about what would be discussed. It's more of: bring awareness, and as I said before let other LGBT players know they aren't alone. In Fitness and Health they mostly talk about whatever lol
Also, there are trolls in every chat. I'm sure that will never change.
