OK, not illegal, but....... the state this week voted a new cirriculum for high school history that will block any "uncomfortable or wish it wasn't so" history to be taught. Only the happy stuff, free market triumphs, patriotic stuff.
Earlier this week Denver teachers had a sick call in day, yesterday students walked out of a number of high schools and protested what they call "censored education" and creating a "secret history to be determined by conservatives".
I wonder if they will expel students for asking about Watergate, or Tea Pot Dome, the New Deal, or the whore house George Washington and his officers frequented? Maybe the gun screening at the door will also look for old history books, with their stories of race riots and slave ships?
