Schools in some states aren't allowed to discuss any topic that creates "discomfort, guilt or anguish on the basis of political belief." Which means they can't teach about slavery or manifest destiny or any other aspect of American history for which an honest, critical look might make white people uncomfortable. Texas even wanted to mandate that 'slavery' be referred to as 'involuntary relocation' and slaves themselves as 'workers' in textbooks, and Texas teachers are forbidden by law from teaching that slavery was part of the founding of the US, they can only teach that it was a "deviation from American values."

It's a bit more than mildly problematic.
