I don't hate any teams as much as the hate I feel for the Cardinals and Cubs. To be honest, I hate the Cardinals far more than the Cubs, but that stems from the 1982 world series. I was a senior in high school at the time, and it is still with me today. It always will be until the Brewers can finally win one.
I hate all teams that aren't the Milwaukee Brewers, but some more than others. My loyalty lies with one team and one team only. All other teams are the enemy.
I'll never understand how anyone can claim to be a fan of more than one team, for any reason... That ideology makes zero sense to me, and you simply can't convince me that you can like more than one team.
It's one team per sport, and one team only.
