Sigh. When I was a kid, they actually taught critical thinking, despite so many of my generation (GenX) not learning it. Today, I gather that they teach kids to just “accept” when the teacher makes no logical sense.
Isn’t it interesting that first the Communists, then the National Socialists, took up the “don’t think, just accept” business and now it’s been taught in schools for at least a decade?
