It quickly is becoming standard operating procedure for the "Occupy" crowd to invade the speaking engagements of other people to shout them down. Today it was an interruption of Rep. Michele Bachman in a South Carolina speech. A few days ago it was disruption of a speech in Chicago by Gov. Walker of Wisconsin.
The media that looked really hard to find something distasteful or bigoted at Tea Party gatherings have been pretty lax on these palpably anti-democratic mobs. The experience of verbal violence is frustrating for speakers and for audiences, of course. However, the disruptions do provide an unintended message of their own, a lesson of their own and a powerful political commentary. Check out the history of 1968.
