Jon Stewart tears open Bill Bennett on gay marriage

Bennett: Well I think if gay..gay people are already members of families...

Stewart: What? (almost spitting out his drink)

Bennett: They're sons and they're daughters..

Stewart: So that's where the buck stops, that's the gay ceiling.

Bennett Look, it's a debate about whether you think marriage is between a man and a women.

Stewart:I disagree, I think it's a debate about whether you think gay people are part of the human condition or just a random fetish.
