The guy is pretty mild and has no I'll intentions. His biggest fault is he dared to speak his mind and has nuanced positions. As you said, most of his detractors never mention any of his positions and take his word out of context. "So what you're saying is.." is usually their MO. And that's sad because of how transparent it is.
Sorry I missed this earlier.
I think he's curious, self aware of his limitations and tries to keep an open mind. So while he's not some genius he applies himself and does his best to absorb the information coming his way. That puts him head and shoulders above high IQ people who don't do their due diligence as it comes to thinking things through. Rogan is like me; pretty average but makes an effort to do the best with what he has.
And yeah, I had a bad case of second hand embarrassment for Rubin that episode. Dude came off like some basic under informed college student.
