Cure for that, like so many other things, is communication and open dialog between responsible parents and their kids.

We talk to our kids about most everything, and have gone through communism, Marxism, etc, debunking it early.

My youngest, when she was in fifth grade, out of the blue asked me if Hitler was so bad and did so many bad things, why did people follow him?

What commenced next was a 2.5 hour discussion on his life, experiences from WW1, and topics such as politics, manipulation, economics, culture, religion, etc.

PARENTS, teach your kids this stuff or others will! And maybe not the way you want them to learn it!
