American school books being re-written by insane fundamentalist republicans

I haven't seen this film yet, need to find it first. But it's a really important subject that I've mentioned a few times in articles I've posted- these crazy conservatives, who think that there were dinosaurs on Noah's Ark, are re-writing all US school textbooks, denying evolution, denying slavery, etc. These text book suppliers basically control all the text books used in all schools in the USA.
