And here’s an interesting bit from a different interview with Silverman about that particular exchange (skip to 4:15):
I’ve heard from other sources that Bill O’Reilly is actually very intelligent, quite contrary to his on-air persona. But is this really a good thing? One might be tempted to think a little better of O’Reilly when they learn that what he does on TV is mostly (all?) an act. But is it really better? Is it better to have an intelligent, educated person poisoning the minds of Americans and damaging their country for personal fame and profit than it is to have an idiot poisoning the minds of Americans and damaging their country because he is an idiot?
I think that’s worse.
