Yeah, he was the first one, and I had to leave all things HP (and even my formerly beloved actor Rickman) behind. After only a month in SGA I already privately ranted "Don't Snape the McKay" and it never stopped and has gotten worse now the show is over. I hear House is the same, and no matter how many people point out that nastiness in itself is not sexy or cool, the pattern is transposed on every fandom.
