South Park vs. Scientology
I don't want to get into all the preliminaries. Get Religion has been covering this (among many others). I'm just noting Get Religion's coverage of last night's episode - if you've been following this story at all, you really have to see this. In my comment (not to toot my own horn) I link to You Tube segments of the ep. Seriously - if you know at all what I'm talking about, click the link, then go see the segments. South Park is terribly profane, vulgar, etc., etc., but they are brilliant as well - probably the best current demonstration of the First Amendment I can think of.
