I have been stupid in my life and, even when I got a bit smarter, lived amongst brilliant people relative to whom I was stupid, so being stupid is not intrinsically bad, it can be a base from which you work to be less stupid.
It's when an actual movement of people comes along and says YOU MUST BE EXACTLY AS STUPID AND AWFUL AS WE ARE TO BE A PROPER PERSON AND ASSIMILATE INTO A GODLY UTOPIA OF GRINDING HOPE-STOMPING STUPID that you should do the work to make sure those people never ever have an iota of influence on anyone else's life.
