Any specific examples? There are things I disagree with them on (mostly their Libertarian political views), but for the most part they tell you they're just fucking around when they're not being totally scientific with something. And for the most part, they're debunking crazy stuff that has no chance of being true anyways, like tarot card readers, psychics who claim to talk to the dead, creationism, feng shui, haunted houses, etc. so I don't think they're obligated to take the credulous side seriously at all. If you want to believe in woo-woo nonsense, yeah, obviously you're not going to like the show, so go watch something else, but it's very entertaining for those of us who don't believe in that kind of crap, and that's really the whole point. They're in show business, they're not scientists.
