You know what I find hurtful. That once my ancestors were millions strong across the land. That children are taught they were a primitive people when in fact they were an advanced culture with large cities.

What children are these? I've never been taught a negative thing about Amerindians (or whatever term you want to give them) in school, but many positive things. Technologically, only the Central American tribes, and some South American tribes, were advanced. Mentally, they were, and are, no different than Europeans, despite not advancing as far in other ways due to location, population (and consequently lack of competition), and many other things.
