I'm not sure anyone claims that EVERYTHING Cesar does is wrong - people just object to some of his methods which they consider cruel and/or ineffective in the long run as well as some baseless claims he makes.

And for anyone who believes that having a TV program validates anything about a man or his work I have a bridge in NY to sell. I mean who are you going to trust when it comes to, for example, physics? Roadrunner or a physicist who doesn't have his own TV show?
