I listened to the Jon Stewart bit about Spotify and Joe Rogan...
Stewart never once defends Rogan's misinformation, he's just saying that Rogan is someone you could engage in a productive discussion with.
I disagree, while I don't think Rogan is necessarily a bad faith actor looking to specifically to sew discord, I do think he is a massive moron who will continue to spread bullshit even after being corrected and agreeing with the correction because he's just a huge meathead idiot.
Either way, Jon isn't taking a "centrist" viewpoint here he's making a specific value judgement about a specific person.
