That’s what we did at my Highschool. Our prof taught us about various religion, including Lavey’s Satanism.
I’m from the Midwest and I took AP World History which included learning about: Hinduism, Zoroastrianism, Judaism, Christianity (origins, Catholicism and the Reformation), Islam, Buddhism (& Zen Buddhism), and Taoism. Non-AP world history students would’ve also covered some of those too. And this was a public high school.
