Joe Rogan is a very agreeable interviewer. He is agreeable with almost every guest he has, which is why he sometimes appears to share political views with everybody he has on. He's pretty regularly accused of adjusting his own beliefs to align with his guests.
He has a lot of right wing type guests, and his agreeable interview style leads people to believe he is also a right wing type guy. But of course when the Twitter guy came on, he was called a shill. When he criticized Alex Jones, he was accused of being a shill.
Hell, even in this thread he is being accused of lying about being fairly liberal to save his career. Guys, news flash...Joe Rogan's career is not dependent on liberals. If anything, it's dependent on his Internet-based fanbase that appears to lean clearly to the right. Just read the thousands of Youtube comments sometime. His other job is working for Dana White. No comment necessary there.
The fact is, he's just an agreeable guy who is fairly easy to sway one way or the other. That style is part of the reason for his success, since you can literally have his show on in the background and not hear people shouting at each other constantly. It comes back to haunt him at times because he has a wide variety of guests on who sometimes spread untruths and he does not have the expertise to condemn them on the spot.
But he's just Joe Rogan. The guy from fear factor. In my opinion, if you don't enjoy his show or his guests, just don't listen. But when people do criticize Joe's willingness to have hacky guests, Joe's fans should be more accepting of that criticism because there's obviously truth to it.
