I'm fine with people who really just don't know stuff. But they should really listen when you try to explain something to them.

You're talking about mostly religion. Not one specific but for all of them to work they have to dumb people down, otherwise why would you follow crazy rules if you can have your faith at home without crazyness?

I believe that in a far future, as humanity gather more and more knowledge keeping religion up will be kind of hard, but until them we will have to go through the "dark ages of christianism" where our lifes will be controled by some old conservarive people. But they will die out.

From what I've heard, this is mostly a US phenomenon.

No.

It’s human nature to want to be the best, the most loved, the top dog. It helps to propagate the species.

If someone is smarter than you, it digs at the very core of that, and becomes a threat.
