Why was a fat chick not allowed to sit in the audience of American Idol?

I had heard about this on the radio and thought it was a bit ridiculous. I actually looked more into it and noticed the chick was not even that fat. I guess this is how California, Hollywood in general acts. For years I have heard that California is ahead of the so called "curb: on everything. I should question their intelligence though. These are the people who voted for Arnold Schwarzenegger for gov and keep voting in Nancy Pelosi. Just because a girl is a little thick does not mean she cant sit on an audience. I mean hell they let Rosie O'Donnell on TV and DAMN. Ryan Seacrest is the biggest douche in the world anyways. This is a lame show that should have been taken off the air years ago.
