Oz is great. He's entertaining but also a hell of a lot smarter than he makes out. He gives a lot of people platforms, yes, even sensationalists and quacks ( and you can put Taubes in this category). But ultimatly, the amount of guests and view points that get aired on his show present the opportunity to set many people down a healthier path.
It's also actually kind of funny how some people here get so outraged by him.
