I am not sure if this is good news or bad news, but it’s pretty clear to me that the purpose of school is to teach kids to be PC. Because how else will you do it? Think of all the major shifts in the social mores of the US: schools were the focal point for civil rights, for example. Evolution plays out in schools. And now, LGBTQ rights are playing out in schools. Schools teach kids how to succeed in a world different from their parents.
