I did learn Real American History in high school. It was very rigorous and way above my head. I think it was the hardest of all my courses and involved reading tons of original documents and letters from presidents and congress etc. I think I got by with a B.  In any case, until this day I find USA history to be very difficult.  I gained a great appreciation for the USA and the tremendous efforts and work that it took to make a free and decent society. That made more even more sad as I see the whole thing disintegrating under my very eyes.
