Huh.
When I was in high school, we only knew about the tragedies of the First Nations (because where I live, that is what we call them instead of Native Americans) from stories of the British betrayal of them to the residential school systems.
Sorry to be off-topic, but I really have to ask - are you American? If that really is all your highschool education has taught you on the subject then they glossed over
quite a colourful list of US misdeeds. (though that might be understating it) Which is strange since the US had
such a similar school policy of their own. In my experience, the current highschool curriculum in Canada taught me of our residential school system and the cultural genocide that resulted from it - in addition to the trade of alcohol to various First Nations groups by the HBC and North West Company during the fur trade. (which turned out to be a rather bad deal for them) In any case, if American curriculum truly only teaches the British/Canadian side - well then...
Sort of on-topic though, as a highschooler still, the War of 1812 is taught as neither a US nor British victory at all - just a 'the British were too busy in Europe to actually deal with it.' (if anybody is wondering)
