For instance, as an ESL teacher I am required to use the Highpoint curriculum, which is rife with articles on the evils of nuclear power, the dire emergency state of our environment, and of course, America's Racist History. They're supposed to write a short essay about how FDRs social programs saved America from the Depression.
Then the mandatory state tests are full of essays about the evil rich and the noble poor, more about the racism of small-town America... the kids recognize pictures of Martin Luther King Jr on sight but I doubt they'd recognize Thomas Jefferson. And on and on.
"...more about the racism of small-town America..."
If you have a link where this is documented, I'd be interested in reading it.
