Why would they invite him in the first place. It once was a conservative college...Guess times have changed...
Interesting how people complained by writing letters and speaking out. There was no violence and presumably no threats. If Ayers had spoken I doubt any right wing groups would have confronted him with intimidation. Compare that to how Karl Rove was treated recently. Or the tea party rally in Searchlight NV.
As Pat Buchanan said too, we hear a lot of nonsense about right wing violence and hate. Yet “the One” his own self is friends with a lefty who blew up buildings and doesn’t regret it.
