Honestly, I think nowadays college makes one stupider.
I was forced to read Things Fall Apart my Sophomore year of college, the black Nigeria Rutgers University professor that taught the class was a through and through Marxist. She would go on and on to the point I once got up and walked out of her class.
Things Fall Apart, as I recall, doesn’t really feature racism in a modern standard, but shows culture clash.
Outside of engineering, college has made people dumber since the sixties.
