My philosophy on this is that we all share a common mania, some more than others.
I think about the Twins at random times during each day, even the offseason, and I check at least 3 Twins websites every day, even on Christmas day. I always want to watch the games and I always need to know the score. Some fans are less hard core than this, and some are more hard core.
While I may completely disagree with what some people say here, the diversity is enlightening and from what I have seen, the debate is generally civil. But it does not hurt to remind ourselves that the most abrasive Twins fan will always be more of your ally than the nicest White Sox fan.
