I remember being taught that the KKK was bad. I liked the costumes, though. Looked pretty bad ass to a kid. Like a mean ghost. We were also taught that Lincoln was a great man. Primarily for freeing the slaves. We were taught that Nazis were bad and that America was great. So is God. They never said which God.
We were taught about the civil war and what it was about. We were never taught that the South was "bad" but that slavery is bad. Kids are smart enough to figure the rest out in their own heads.
I watched the Nixon impeachment in class.
Rocket launches.
We were taught not to pollute.
We were taught to prevent forest fires.
We were taught about women's liberation. The boys thought it was great to see women burning bras. We were taught to respect women. Never to hit women.
We were taught about animals and how awesome they are. We were taught about extinction of species. We were taught about both evolution and also about the different religions and what the basic beliefs are.
We learned about terrorism.
We learned about machine shop, auto shop, wood shop. We learned photography. Math, physics, geometry. Writing, English, spelling, grammar. Computer programming. Typing. Accounting. Home economics. Farming/Ag. The list goes on. Not to mention football/baseball/basketball/volleyball/wrestling/track etc
I am talking education in the 60s/70/80s
People make fun of the US education system. It was superb. It only headed downhill as budgets were cut, discipline was removed, classes were overcrowded, teacher pay was slashed and the leftist agenda crept in.
