I've watched all of the media that I use to love turn to shit in the last decade. Myspace was great, for a time. Facebook was too. Digg. The Daily Show with Jon Stewart. Colbert. Chapelle. JRE. YouTube. Reddit. They all got mainstreamed (or ceased to exist altogether) and they all lost their edge.(self)
I'm not a huge Rogan fan but I listen casually sometimes. He's always come across as pretty genuine to me. If you can read between the lines you probably have a good idea of his beliefs, but it's not like he invites people on the show to just argue with them.
