Glenn Beck is a kind and compassionate individual. Mike Malloy is a raving f'n lunatic with a microphone. The right's closest comparison is Ann Coulter or Mike Savage, but even they pale in comparison.
I wouldn't put Coulter in the same class as Savage.
While Ann sometimes goes a bit over the top, she's still solidly on the conservative side, and is usually trying to be funny in the snarkiest sort of way.
Savage, on the other hand, seldom seems to be in any sort of good humor, and careens wildy between conservative and outright moonbat, sometimes on the same subject! When he's having a good day I can listen to him, but the good days are fewer and farther between al the time.
I've only caught Glenn Beck's radio show twice, since the nearest affiliate station is at fringe reception range, but what I've heard I really like.
