Yes, Materialist.
Exactly, except I'm not so sure they didn't create them. Female liberation scares the living bee-jebus out of fundamentalists.
I once read a high school textbook about social movements in 1970's, and as many people know, US high school textbooks have to be approved by a committee in rightwing Texas.
Texas buys more schoolbooks than any other state except one, and California has had its hands tied by special interests and tax policy --- so publishers publish for the Texas market rather than create 2 versions. That committee is why the US still has creationists in large numbers, and why Hillary's candidacy will not be included in high school history books.
The book I read included lots of material about Vietnam, black male voting rights and had a whole 2 chapters on women. One was a chapter on The Malaise boredom of being a housewife - and the other was how rape cases come down to he said / she said.
I'm not surprised they don't know squat in high school. What makes me angry though is how colleges are selling them out with gender studies.
