While I agree with your point that parents should take an active role in teaching their kids history, I also think a lot of adults need to actually spend time educating themselves because they lack basic historical knowledge themselves. A lot of grown adults don't know why Jackson is on the $20 bill or what the gulags even are. We can't possibly educate the next generation when the current generation is ignorant. We need to have some sort of shift in our society to emphasize the importance history and historical accuracy because our national discourse is severely lacking in nuance and depth.
