What the hooligans last Thursday at my lecture in Colorado were objecting to was a very different kind of invasion-a peaceful, voluntary offering of ideas they were unaware of, didn't want to hear, and thought it was their right to prevent others from hearing. Their intent was to intimidate, to harass, to silence, to dominate.
