George is the host of the show. Hosts do not pick their guests, the station does. He has no more control over which guests are picked than you do.
Also, if he has a strong view towards something, that's his opinion. He does not force anything on anyone, unless he is literally forcing you to watch his show. (I mean, if he's got a gun to your head, then he's forcing his view on you.) Otherwise, he's just expressing his views.
