First, I strongly recommend you read the text of Vanderboegh's April 19 speech. Seriously. It's damned good, and it needs saying and spreading around. I've been known to use the key phrase myself occasionally.
Second, I want you to read this post at The Ultimate Answer to Kings, which carries today's Quote of the Day, because Joel's right:
The people at those rallies aren't the extremists. They're just good, brave people who still believe in the political process. The real extremists stayed home, because they don't.
