Look on the bright side: people are talking about (and thinking about) topics they might not normally be exposed to. The blame for lack of critical thought skills might fall more upon our parents and educators than Joe Rogan.
What's "dangerous" is the intolerance of thought that permeates society right now. We seem to have lost the ability to listen and then respond.
I always thought Joe Rogan might be more of an Art Bell-type personality. Personality, not authority.
