I tend to prefer having a rooting interest in sports. Sometimes that will be against, sometimes it will be for. Unfortunately, my cheer for team right now is Washington :(
I agree in principle, but that doesn't mean I can't have preferences as to which teams those are. After all, I always thought the people who wanted Toronto to be good, for the sake of rivalry, were completely insane. They're good, and fun, and I hate it. Why couldn't it have been Florida or something?
