Fisk V.S TSU

I'm sure that in no matter what city of the U.S, where there are two black schools near each other there will be some type of hatred between the schools, my question is why? Fisk and TSU hate each other there have been so many fights up here that its rediculous. Even at home at the Taste of Chicago TSU and Fisk got into an argument and caused a small riot. Do any other schools have the same issues or feuds? Feel free to say anything but be respectful.
