Confused on the Left, Blinded by the Right (Part II, Blinded)

I'd like to introduce everyone to David Brock, author of Blinded by the Right and The Republican Noise Machine. In Blinded, he introduces himself as a progressive and idealistic young lad who had a rude awakening during his college days in Berkeley. He went to cover Jeane Kirkpatrick's speech to the college, and was deeply disturbed when protesters interrupted her until she was forced to leave the stage:

The scene shook me deeply: Was the harassment of an unpopular speaker the legacy of the Berkeley-campus Free Speech Movement, when students demanded the right to canvass for any and all political causes on the campus's Sproul Plaza? Wasn't free speech a liberal value? How, I wondered, could this thought police call itself liberal?. . . . The few outspoken conservatives on the faculty, and the Reagan regents, raised their voices in support of Kirkpatrick's free speech rights. The liberals seemed to me to be defending censorship.

(David Brock, Blinded by the Right, Three Rivers Press, 2002, p. 4.)

This and other incidents burned in his mind, Brock turned from liberal and progressive issues and became a cheerleader for the Other Side. ( He rose in prominence, changing the course of American history as he ascended. )
