I’m pretty sure you can make the same case about things taught in the US about vast swathes of American history like Christopher Columbus, the Louisiana purchase, the pilgrims, etc.

I’m not even American but I’ve noticed the bar’s pretty low after living here for years.

On one hand, we probably shouldn’t be making pedagogical policy based on the most gullible in our society, but on the other, everyone is gullible when they’re young and many continue to be so afterwards.
