This has nothing to do with him being white, straight, or a male. He wrote "diversity is perversity".

Although I agree the man was foolish to write such a comment, this Country is inching closer to a state of social facism. We are using institutions to force certain ideas upon people, and severly punishing them for disagreeing with the popular opinion.

If you want another example, read the reactions by certain "journalists" to calls for immigration reform and border security.
