Lex is a fantastic host. Probably the best one in podcasting right now. He pushes back all the time, but knows when to move on when there is disagreement. There's nothing worse than a host who needs to win arguments.
I appreciate that he lets guests speak without any need to conform to a narrative. I can make my own opinion. I don't need the host doing it for me.
I truly don't know where you get the impression that there is no exchange of ideas. I've experienced him going very deep on many, many different topics.
