In his gutless and stupid decision to bow to the PC police by covering (but not removing) the Columbus Murals, he has managed to irritate both sides of the political spectrum. Forgetting about what side of the controversy you may be on, it is sad that the University has a man at it's helm capable of screwing up a situation up this badly while at the same time being used as a PR tool of the left.
As art, understood in historical context and intent, the murals would only be offensive to people of ignorance.
People looking to be offended. They would probably be offended by the American Flag or the Cross.
