I blame democracy. We're beholden to each other's stupidity.
If you're wrong about something, you can impose that ignorance on me via the electoral process.
If there's only a small group of you, unlikely to grow, then it's not a big threat, but in the battle of worldviews it's tribal because if I don't control the state to impose my beliefs on you, then you'll control the state to impose your beliefs on me.
It's sick, and wrong, and its one of the many reasons I stopped voting, and encourage others to stop too.
