As for the “which fan base is racist” discussion. It’s a zero sum game. Both Pennsylvania and Iowa have a ton of racists. It’s a sad fact of life that is mostly true of the majority of US states. Maybe the brand or overtness of racism changes in different states, but it’s still there. I’m sure PSU has tons of gross fans, I’m sure Iowa does as well. Don’t think it’s fair to say either defines a fan base.
Additionally, racists tend to be a lot less racist when they’re rooting for an athlete on *their* team. Always amuses me how that works.
