It's really not fair to the shows and such that they are judged off of the fandom. I watched Hetalia before I had ever been to a con and thought it was an entertaining show. Then I saw some people in the fandom running around dragging flags on the floor. It made me cringe. I do know some really cool people in both the Hetalia and Homestuck fandoms though.
Right now I am working on a Mey-Rin from Kuroshitsuji cosplay and I'm slightly worried about wearing it after seeing the fandom. It's not as big as Hetalia/HS but it has its problems as well. The fandom seems to be dying down a bit though so I'm sure it will be fine.
