My perspective on Rogan is that he possesses just enough intelligence to be passable in his milieu, while possessing a warm charisma, yuck-yuck likability that endears the audience. I loved him in News Radio … 25 years ago.
Trouble is, Rogan’s milieu is disproportionately influenced by right wing ideologues and grifters like Milo, Peterson, RFKjr, etc, and those folks see Rogan as the empty intellectual vessel he truly is. I think Rogan has had a deleterious effect on society by contributing to this current hard turn to the right by young men, which is chalked full of messaging about male entitlement, female inferiority, xenophobia, and creating images of “men” that could and should be criticized for how broadly unrealistic they are for 90% of young men. That said, I don’t think he’s a “bad guy”, I just think he’s kinda empty.
Upshot, I’m in favor of Harris going on Rogan with the condition that it’s Rogan alone involved in the interview. I think he’s easily persuadable, or at a minimum, he’s easy to soften, and that goes a long way with young men.
