He’s being called a neanderthal because he seems to agree with a lot of fringe opinions.

I mean that's just a symptom of the biggest complaint about him. He's really gullible. He's not malicious, but god damn he does not notice a liar when a liar is in front of him. Genuinely I do love his long form content, I love how people can go off topic with him, but some of the people he brings on really should be going in front of Jon Stewart instead.

Like... here's an example of someone clearly lying, dodging questions, and genuinely being sketchy. He's gotten a bit better but would Joe Rogan push this hard against somebody? If someone dodges his question, how well does he bring the topic back to it? Joe Rogan is great when everyone is there in good faith, but would you want him in your corner if you're stuck in a timeshare conference?
