It is backwards. It’s rather often that, as an adult, I learn something that is fundamentally contradictory to what I learned in grade school. Usually it’s the framing of events, details that got left out… They paint a story that usually ends with the US saving the day somewhere. Kids learn more politically accurate stories from their family members. Teachers will shush down a kiddo who speaks up on these details, because “professionalism” means yielding to the potential that any one of their student parents might not find the alternative material acceptable.
