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.
My brother also sent his kids/my nephs/nieces to a private Christian academy. All my brothers and sisters were the same. My parents were not the richest but they busted their rears to make sure we didnt go public. It became like a family tradition LOL.
But unlike today, we wore a necktie and coat and this was during the 90’s. The best thing I guess about it was that the other public school girls in the district knew who we were and it was not even a problem to ask them out for dates haha must be the uniform
