This just reinforces the need to have real talks with our children about what propaganda is, what "history" is, and how to be critical thinkers and not believe everything they're told.
There is no such thing as "insert marginalized group here" history, only our understanding of past events and cultural lore, none of which is necessarily true or complete in our understanding of the facts.
The government day cares and indoctrination centers will continue to do exactly what they were designed and incentivized to do - train our children to be slaves to the state. The only thing we can do is deprogram and retrain our children (gently, of course) to see beyond the textbooks and teachers.
