Frankly, I'm looking at this clip and what I come away with is: no one actually said they wished for a terrorist attack, they were just saying that's what it would take for the (presumably) American people to finally 'come around' to their way of thinking. Not exactly the same thing. Fantastically stupid and insensitive, but not the same.
That said, I've no doubt that both of those guys are assholes that hold all manner of opinions that I object to. I've never actually seen Glen Beck before today, but from what I've heard he's generally understood to be one of those hyperbolic troglodyte types that are so easy to hate.
I say meh. There may be crazy folks out there who take people like this seriously but they are just as disenfranchised and voiceless as the rest of us.
