I've seen people be more rude to those who are cosplaying from HS, than I have seen HS cosplayers be. The last con I was at, at a Homestuck photoshoot this guy(who wasn't cosplaying) stormed in and said "Oh god, look at all the Homestucks!" In an incredibly rude voice. All of us just kind of looked at him like, "really?" and no. He wasn't playing around, he would go around commenting "on look, another homestuck" to people when they walked down the hall. It was incredibly rude.
It's just disheartening when people glare, roll their eyes, or what have you just because you're cosplaying a Homestuck character.
