I don't understand why everyone is so "outraged" by Dr. Oz. The guy makes a lot of money pandering to insecure women. It's his job. Today he tells them that being fat is beautiful because overweight people "bring a different life experience" (whatever that means) and tomorrow he'll be selling them on some magic weight loss pill. It's no different than a defense attorney representing a criminal. You don't get paid big bucks to say things that you actually believe in.
As for the "Roosh V" guy, I think he did reasonably well for a guy who is not a professional public speaker and was very clearly set up by the producers. They tried to paint him as a monster but he responded calmly and managed make a few good points.
