Okay, I found something negative Media Matters had to post about Beck's Founders' Friday shows. It was about the last show, Women of the American Revolution. Media Matters posted a 10 second clip of Beck's opening for the program. Somehow, this is racist and sexist according to comments about the ten second clip.

If you missed the show, here's a link where you can watch the entire episode and decide for yourself what you think:
