Pat Buchanan doesn't think TV personalities should be accountable for their rhetoric

Here's Pat Buchanan on MSNBC, moments ago:

If David Letterman had said that about Sasha Obama and Alex Rodriguez, he'd be out of a job now, and he'd be begging to get his job back. But Sarah Palin and her daughters are fair game. And it really does show there is a terrible double-standard here. But I will say this: Letterman has apologized, and she has accepted it. I hope we don't go on with it. I think we ought to go forward, because Letterman is less of a problem, frankly, than the people out there who are the censors, trying to get people on the left or on the right thrown off of TV shows because of what they say.

Shocking that Pat Buchanan doesn't want anyone to consider his rhetoric in deciding whether to keep paying him to talk on TV, isn't it?

But what criteria do Buchanan think people should use in assessing whether someone should be on television, if not “what they say”? Or does he think TV Pundit should be a lifetime appointment, like the Supreme Court?
