Smart people and those who imagine themselves to be smart tend to be authoritarian.
That’s because they believe they know what’s best for you.
They see nothing wrong with forcing their ideas on you, however they can. Including through the guns of government. They see themselves as the Elite, better than the rest. Better than you and me.
They mistake “smarter than” for “better than”; “more kindly and understanding than.”
They are nothing but bullies. Instead of being physically bigger and stronger like the playground bullies, they are (perhaps) mentally bigger and stronger, and they use this to beat up on others who are at a disadvantage.
Oh, they’ll believe they are doing it for your own good. Which means they aren’t as smart as they imagine themselves to be.
It would be nice if these smart people were smart enough to leave people alone to make, and learn from, their own mistakes. And smart enough to know where their rights end and the other person’s rights begin. But that would undercut their feelings of superiority, and they can’t allow that to happen.
