What's the reason?
They claim the course only teaches students "what is bad about America," and fails to teach "American exceptionalism."
Nonsense. No history course does such a thing. But these self-proclaimed patriots want to whitewash American history so that all of the ugly stuff they'd rather not think about would just evaporate out of textbooks. Poof!
Millions of Native Americans killed upon our ancestors' arrival? Never happened. Slavery? Lynchings? Japanese internment camps? The KKK? Segregation? Voter suppression? Nope. Never happened either.
This whole "American exceptionalism" thing is insanity. We are to teach kids that we are superior to others around the world simply by virtue of having been born here. We are the "city upon a hill" that no one else can match, they like to claim.
Baloney. But it sounds nice in political speeches.

Colorado students walked out en masse. Oklahoma students and teachers need to do the same.
American history must be taught in its entirety, including the good, the bad and the ugly. And there's plenty in each of those categories.
