Yin and Yang. Heaven and Hell. Good and Evil. Real life is full of dichotomies. Oftentimes, they even manage to bleed into the areas of our lives that may seem inconsequential to outside observers.
I imagine every reader here pours way more energy into their fandom than could be considered "sane". You are, after all, reading this article on a Bama blog two months before the season even starts. That kind of commitment of energy and passion can't exist on only one side of the scale. Invariably (yes, Glen, if you're reading this you are the exception), our passion for Bama football is necessarily counterbalanced by hate for other teams.
