I feel like this is a problem in general.
I was talking with InfiniteNine the other day and we both agreed that the Fatal Frame V thread was basically a lost cause since it just became a discussion of an optional, post-game costume with people quoting the picture and going "MAN THIS IS SO SEXY."
Which, you know, fine. Whatever. Think whatever you want is sexy, I'm not here to judge, but keep it in your goddamn pants, would you please? You're allowed to have whatever preferences you like, but just because you're on the internet doesn't mean that you've removed yourself from polite society and suddenly anything goes.
The creepiest parts of communities have hijacked the conversations to be about what they like, how intensely they like it, and it gives everyone a bad name.
Not only that, but stinking up an entire thread with "waifu" talk or whatever isn't great for either side. You can't even discuss parts of the game that have a relationship mechanic to it, like FE: A or the newer Persona games, because it's taboo all of a sudden.
Basically, I just wish people wish people would use good judgement before changing the entire dynamic of a thread/community. It doesn't help anyone.
