I saw the C-SPAN show, too. Three observations:
1) If this is the face of the Left today, they haven’t much of a future. Pathetic.
2) What’s with the burly security perimeter around the dude? The audience was whooping and hollering for the guy; there was no threat of disruption or harm to the speaker. The security people, with their paramilitary looking vests, made the thing look like a low-rent Nuremberg rally–which is what it was, come to think of it.
3) When the Italian-American chap asked why he shouldn’t have his free speech rights to hold a Columbus Day parade, Churchill offered an absurd explanation involving the Ninth Amendment and international treaties. To repair once again to the Gertrude Stein-on-Oakland remark, “There’s no there there” with this guy. It is all posing and hatred. At least the SDS in the 1960s had a manifesto, the Port Huron Statement. This guy probably writes in crayon.
