That's not Hanania's podcast.
People left of the far-right have to use their fucking brains about this shit. There's some nuance for who someone should engage with, depending on their platform, the topics at hand, and your ability to speak to them and their audience. If you are Pete Buttigieg or Bernie Sanders, you can go on Joe Rogan. But if you're fucking Dr. Sanjay Gupta trying to promote vaccines, not prepared for a hostile debate and thinking you're going to get an honest interview, stay the fuck home.
But there's one hard-and-fast-rule and that's this: Don't debate nazis. Don't do public appearances with nazis. In fact, just don't talk to nazis. Richard Hanania is a nazi, no matter that he pretends otherwise now. He's never actually disavowed anything he used to say or believe, he just thinks it's more beneficial for him personally and his cause if the nazi shit seems more intelligent and sophisticated. That is his project. When you speak with him to talk politics and sell your political book, you're legitimating him as an acceptable public intellectual figure. You're legitimating his ideas as acceptable public ideas. You're aiding his project.
