This private school student never took this crap. Our teachers were mostly rightwing zealots aka normal people.
I attended public schools and never saw this garbage. I didn’t have it in college either as I had the most conservative of conservatives as my US history professor. One of my daughters had AP US history, and I did not come across anything like this in her text, but I did not go through the whole text. The teachers around here are mostly very conservative in the public schools. But they do use the materials recommended by the AP folks. Maybe they will reject this text.
My oldest sons attended a public high school elsewhere. Lets just say that their US history teachers (not AP) were flaming in more ways than one. They had different teachers, and after a semester, I removed them from the classes. They were one year apart. There were not a lot of conservative teachers at that school. My oldest son found the best of them, and he learned a lot from them. My second son was a rebel. He still is. He was not well loved by his liberal teachers. We moved before his senior year, and he attended a private Christian school. That was such a blessing for him. Our teachers at our public schools now are almost all attached to the military in some way whether they are spouses of military folks or retired from the military.
