That’s the first time I hear of a radical leftist being dis-invited to a University for being too much of a hater. Kudos to the U of Pennsylvania, for a change!
Nope, it’s just more of the same fail. Universities should be places of thoughtful discussion and debate. Make a liberal back up their beliefs with facts, logic and experience. They can’t.
The best way to defeat them is to expose the vacuity of their ideas.
