Is this a "normal" Rivalry Complex?

Of course its normal. Its called "opponent hatred". Think about it. The Bears are direct rivals to the Packers and have been so for years. So its completely natural for Bears/Packers fans to have a dislike or even a hatred for each other. For myself, I am a Colts fan. I don't really feel this way about teams within the AFC South. The AFC South doesn't really have a competitive rivalry of that nature like the Packers/Bears. There are a few great rivalries, but not in the AFC South. Although the Jags do give the Colts a good run every now and then. But I kind of feel the way you do when the Colts play the Patriots. That has become more of a recent rivalry because of how the Patriots have unfortunately beaten the Colts in playoff games before the Colts last super bowl win. But don't worry about it. You are a normal football fan.
