Here's my two cents...I'm a conservative Christian, and most likely I'm somewhere to the right of Beck on most issues. My wife has listened to Beck for years, back before the Fox TV show days, and still listens to his radio show semi-regularly, as well as regularly checking out the Blaze and GBTV.
I did enjoy Beck's TV show and enjoyed his "instructional" shows re. US history and the Constitution. He introduced us to the historian David Barton, who I think is tremendous. As for the radio show, my job doesn't allow much time most days for listening.
That said, there's always been something about Beck that's raised a bit of a warning flag with me. I can't quite put my finger on what it is, but I've told my wife many times I strongly suspect she's going to be very disappointed in Beck at some point in the future.
One thing (not the only thing, but one) that bothers me about him is that while he talks a good game about his faith, he's quite careless about his language on the radio. I know disliking swearing is a quaint anachronism in our "culture," even among contemporary Christian circles where vulgarity is almost encouraged these days. Even so, I think anyone who's serious about the Christian faith and following the life principles of the Bible is not going to be habitually using vulgar language.
Beck's show some days is as bad, language-wise, as many prime-time TV shows. I've had to turn him off more than once. Which is a shame because most of the time, he's saying things that need to be said, and that most other "conservative" talk radio people won't.
As far as Beck apologizing for being "divisive" or "tearing down" on his TV show, well, conservatives really have to stop buying into the liberal propaganda that discussing what we think is wrong with liberal positions is "divisive." That's just wrong, and certainly the libs haven't been shy about either stating their positions or ridiculing ours, and us. There's absolutely nothing wrong with pointing out where you think peoples' positions and thinking is wrong, as long as you stay civil and criticize the positions and ideas, not the person.
