Per Rich Casebolt, a regular commenter at American Power blog:
See? So the reason they have to shutdown the debate is because the congressmen involved use data that conservatives don't agree with. And rather than use these forums to highlight these differences and set the record straight, they have to disrupt the event and make sure that no one can be heard. And that's because if normal people (ie, non-conservatives) hear conservative arguments, they realize how stupid they are and prefer the Democratic plan. And while shouting makes them look stupid, rude, and angry; that's still preferable to what happens when they explain themselves. It's as simple as that.
Sorry, Biobrain, but when the answers to the questions are based on falsehoods like the "47 million uninsured" that includes illegals and millions with means who CHOOSE not to purchase insurance, the civil discourse of the Q&A session is counterproductive to the public interest.
We've tried civility ... and all that has done is let the intellectually dishonest frame the debate, giving their lies (and yes, unlike Mr. Bush re Iraq, these ARE lies) the unmerited respect of civil repetition.
And yes, they're still trying to unlose the debate over Iraq.
