If anyone ever tries to tell you that most colleges haven’t been taken over by liberals, you can always remind them about this lovely display by students at CUNY. David Petraeus was hired to teach there, and this is how the students have decided to treat him. So much for respect for elders, or professors! Well, perhaps none of the students that were involved actually are enrolled in any of his classes. Of course, even if they were, it probably wouldn’t matter. Petraeus would undoubtedly have given them the grades they actually earned.
