@Auspice Sure, but it's based on our perception that aforementioned PTSD character is only using it as a 'quirk'. Sometimes that's true, but sometimes it's just our inability to see deeper.
But at the same time... I don't really care. You want to play "the gay one"? Fine, whatever. It's a game, you're playing a trope. Whatever. I'd much rather people try to do something interesting and get it wrong than just play the same "basic white guy" over and over.
