The problem is the Marxists write the books.  I bet if parents read what passes today for American history, they'd be hard pressed to recognize it was America they were reading about.  The left has had free reign over education for 60 years.  This is why the kids today can't hold a candle to foreign students.  Jessie Waters from Fox News used to show pictures of recent American presidents to random college aged people on the streets and asked them to identify them and they couldn't.    I bet you could read American history books from the 1950's and never see the words oppressed, social justice, racist, gender, climate change, equity, global warming, injustice, marginalized, homophobic, institutionalized, systemic, repressed, civil right  405a  s, victimized, misogynistic etc.  Today, those words form the lexicon of every subject taught.  This is why the only thing students learn well in school is how to hate....hate their parents, their schools, their government, their country, the police, all authority and those that don't think as they do.  Basically, they learn how to be nihilists and obedient communist apparatchiks.
