I asked about this last night in the open thread, but did not have a source, and no one seemed to have any information about it. The alleged "Open Letter to Glenn Beck" that he reportedly read on his show.
Now that I've confirmed the letter to be his on his website, I've been working through debunking it. It's actually hard to debunk, because really there is no meat, just sound bites. I have to say in some places I agree with the sentiment. Or at least the frustration, but probably not in the same way the author does and certainly not in the way Glenn Beck does!
