Fine Damo, now were you as critical and insulting of tea partiers who shouted down Democrats during the health care debate? The tea partiers were not even acting spontaneously. There were giving written instructions authored by lobbyists on how to disrupt town hall meetings and how to intimidate Congressman.
Rocking the Town Hall-Best Practices
– Artificially Inflate Your Numbers: “Spread out in the hall and try to be in the front half. The objective is to put the Rep on the defensive with your questions and follow-up. The Rep should be made to feel that a majority, and if not, a significant portion of at least the audience, opposes the socialist agenda of Washington.”
– Be Disruptive Early And Often: “You need to rock-the-boat early in the Rep’s presentation, Watch for an opportunity to yell out and challenge the Rep’s statements early.”
– Try To “Rattle Him,” Not Have An Intelligent Debate: “The goal is to rattle him, get him off his prepared script and agenda. If he says something outrageous, stand up and shout out and sit right back down. Look for these opportunities before he even takes questions.”
And if they were arrested I would say the same thing. I believe that the largest difference is between public and private venues...
Nobody has a "right" to make it impossible for others to participate. That is not covered in the First Amendment...
I would note that in the "instructions" they want them to ask questions, not to shout them down and not shut up. In fact, it illustrates a difference between somebody attempting to make it impossible for others to participate (shouting him down and not shutting up) and somebody trying to "rattle" somebody. Stand up, shout, sit down...
One will likely get you arrested, the other probably not.
