Liberal bullies are addicted to the shot of adrenaline that comes with perpetual outrage and the dopamine hit that comes from an exercise of power. “I get to bully you and ban something, and it is OK, because I’m doing it on behalf of this sacred cause.”
And attention seeking can be an element, too. Like imams banning women from handling bananas, calling for new things to be banned is a way to get attention and fame.
Thomas Sowell had a lot of good stuff to say on that issue in “The Vision of the Anointed.”
