While I well understand that things were a little tense when President Obama spoke at Notre Dame's commencement, one would think that grads at this level might have put a little more thought into the counter-protest:

Obama entered the arena to thunderous applause and a standing ovation from many in the crowd of 12,000. But as the president began his commencement address, at least three protesters interrupted it. One yelled, "Stop killing our children."

The graduates responded by chanting "Yes we can," the slogan that became synonymous with Obama's presidential campaign.
