Throwing pies....a new leftist tactic.

The latest way to stop people from talking is by throwing pies. Lately, conservatives have been the target....

There may be a tendency to dismiss the incidents as harmless, if annoying, college pranks, but in the last two weeks three conservative commentators speaking on college campuses have had their speeches physically disrupted.

Most recently, David Horowitz, a critic of leftist political correctness in academia, was struck in the face with a pie at Butler University.

William Kristol, editor of The Weekly Standard, was also hit with a pie, coincidentally at another Indiana campus, Earlham College.

And veteran conservative Pat Buchanan had salad dressing flung in his face at Western Michigan University.
