On the one hand, every country has a fucked up history that they ain’t teaching in classes

I don’t think it is being intentionally obscured, it’s just too specific for elementary or high school education. There’s a chance a teacher could use it as spotlight type thing, but overall, that level of education is too broad.

The US does teach about screwing over indigenous people and slavery… well maybe not in red states. And now the current administration is whitewashing history.

Also, it sounds like those two things are the same hand. What’s your country?
