Left Descends To Food Fights

The American Left, having apparently run out of rhetorical gas and losing every argument it makes on foreign and domestic policy, now has opted for food fights to stop debates. Pat Buchanon became the latest target of the Left’s childishness at a Western Michigan University debate:

Commentator and former presidential candidate Pat Buchanan cut short an appearance after an opponent of his conservative views doused him with salad dressing.
“Stop the bigotry!” the demonstrator shouted as he hurled the liquid Thursday night during the program at Western Michigan University. The incident came just two days after another noted conservative, William Kristol, was struck by a pie during an appearance at a college in Indiana.
After he was hit, Buchanan cut short his question-and-answer session with the audience, saying, “Thank you all for coming, but I’m going to have to get my hair washed.”

If the attacks weren’t so pathetic, they’d be dangerous — and that may yet come as the International ANSWER/MoveOn faction descends further into its immature, neurotic state. I’m no fan of Buchanon, but he does debate rather well, as does William Kristol. It seems that the Left has no answer for their skill, and so they instead sabotage the debate by hurling food. When that fails, as it did with Kristol, what comes next? Smoke bombs? Worse?
Before that happens, expect to see universities quit hosting such conferences, out of concern for student and guest safety. That’s what the radical Left wants; they will brook no dissent from the pseudo-Utopian orthodoxy they’ve spent a lifetime building in Academia, and will fight any attempt to inject reality by any means necessary.
UPDATE: ABC News describes yet another incident, this time at a debate between Howard Dean and Richard Perle, where a conservative got physically assaulted by a Leftist:

Howard Dean, the newly minted leader of the Democratic Party, and former Pentagon adviser Richard Perle made clear their opposing views on the war in Iraq during a debate marred by a protester who tossed a shoe at Perle.
Perle had just started his comments Thursday when a protester threw a shoe at him before being dragged away, screaming, “Liar! Liar!”

Now we’re up to shoes. Paul Krugman wrote earlier this week that conservatives would start assassinating politicians simply out of passion from debating weighty issues. How come Krugman hasn’t written a word about the escalation of actual violence from the Left?
