A buddy i went to high school with had it and behaved very similar to her. Every 10-20 seconds he would make a very short and sharp "hnnnng" noise and his face would wince. When I first met him i thought he was trying to be funny because i thought people with turrets always swore with they had a spams, he told me that wasn't the case and that most people who have mild cases just make a short mumbled noise
From what I have heard it was but a few individuals being obnoxious and suddenly the entire fandom gets the hate for it. It's worse than ponies nowadays, at least ponies are being accepted on here for the biggest part now. Why not homestuck? Why so much hate? You ****** really gotta chill.
I should probably mention that I know next to nothing about homestuck, all I know is that people like to hate on it for all eternity for no good reason.
