What’s bad is ignoring basic biology and letting adolescents and adults believe that their fantasy world is reality and should be accepted by the General Public. THAT is lunacy!!!
Once we have left the innocence of childhood we must accept who and what we are, whether we like it or not. Of course we can still engage in role play, cosplay, and other agreed upon fantasies for their entertainment value, but we accept they are just that… fantasies and games., not reality.
Dr Peterson simply refuses (as do I) to allow individuals with a mental health issue to force us to accept their fantasy world as reality.
