Don't blame him one bit. I feel the exact same way about Carolina. There isn't a group of people, past, present, alive or dead, that I wouldn't cheer for against Carolina until the basketball game was over.

But during the game, go (insert your team of horrible monsters of history here), stomp the Heels.
