I'm a big fan of Jordan Peterson myself and I watched that same Rubin Report interview. Dave Rubin showed great skill as an interviewer. I've been subscribed to his channel since then. He is very polite and even-handed with his guests.
It was a pleasure to read your post relating your thoughts on the interview. I came across your post while browsing the /f/christianity forum.
Had you watched many of Jordan Peterson's videos prior to the Rubin Report interview?
