Clearly you were in the minority as an ISU fan because (as I'm sure you're well aware) there was a lot of butthurt to go around that night. Just like with the student section Friday night. Niang's juvenile actions upset a lot of them, although I haven't heard about any death threats or racist comments from the Iowa fanbase at this point.
That's true, people went totally overboard on it. Although if you want to see some truly vile stuff just follow Pollard or Niang on twitter, doesn't matter what they post, Iowa fans comment on it and it gets pretty bad.
