That is a great video! Basically the history of how America got to where it is today.
STEM is far from immune. I work with a ton of "STEM" graduates and a whole lot of them are very liberal. You wouldn't believe the nashing of teeth over Trump. The really surprising part is that they are working in the defense industry. They have no logic whatsoever (isn't STEM based on logic??? not sure what they are teaching anymore). The company itself has bought in to all the liberal philosophies, too. It's bad.
My uncle recently retired from working for the state. He's a big hunter and trapper. For a part time retirement job, he is working for OSU providing training (i think through the extension). Anyway, he doesn't like it too well... "these are not my kind of people."
Even the "christian" schools are falling in with the culture. My wife and I were very disappointed in the experience with our oldest daughter.
