Bill Whittle lays it out in this video clip. It's well worth your time to watch it.
That's why our society appears to be infested with liberal idiots, democratic socialists, Antifa, radical feminists, and the like. They're almost all the product of the tarnished, propagandistic, left-wing-hijacked American educational system.
For the love of God, if you have children or grandchildren, please see to it that they're given enough food for thought to counteract this inadequate preparation for life and progressive brainwashing! Home schooling is a good start, for those in a position to provide it. A solid family life (including extended family) and exposure to the practicalities (rather than esoteric theories) of life from an early age goes a long way, too. Sending them to the latest superhero movie, or providing them with a smartphone or tablet from an early age, does nothing for them. It merely exposes them to more of what Bill Whittle portrays. Break that cycle. Teach them to be well-rounded, well-grounded human beings first. The rest will follow - and they won't fall into the progressive trap.
Sadly, of course, that means they need well-rounded, well-grounded human beings from whom to learn about reality, and who are willing to exert the required effort to impart that. There aren't enough to go around, these days. I can see that very clearly in the children of my friends. Some are a delight, even in their early years; well-disciplined without being subdued, playful yet polite, the usual childhood naughtiness but tempered with awareness of what is and isn't right, interested and inquisitive about life without being pests. Others . . . not so much.
