On the note of the US Civil War.
Also I am thankful for my Canadian education system in History classes since at least in terms of our own history, we cover pre-Confederation, Confederation, our expansion and the violence out in Manitoba as Louis Riel led Metis rebellions out of fear of Canadian influence ruining their culture. We tried to cover his Legacy, both his detractors and those who see him as a hero for standing up for the rights of an oppressed group. Then we cover the World Wars with the Roaring 20's and Great Depression, then we continue on as far as the semester would take us. It isn't perfect, but at least as I saw it get to High school and I took Canadian history, we sort of looked at both sides of Canadian history, both our "moments of pride," such as us fighting in the World Wars and holding our own despite being a smaller country (including creating a strategy in WW1 to be effective in Trench Warfare, creeping barrage), and darker moments such as the internment of Japanese Canadians, the narrative of oppression of the Aboriginal population, Sir John A's Pacific Scandal, and more. It was... alright-
OH EXCEPT THE FACT THEY SIMPLY GLOSS OVER STUFF LIKE THE RESIDENTIAL SCHOOL SYSTEM! I know the last one only closed in the 90's, so by the time I went to school it was only just recently "history" but it is hard to gloss over... especially with its prevalence for over a century and how it still comes in effect today. It took until me going to University and PAYING for my education to really get details about it aside from "They tried to force them to change their culture in these schools." Which is still bad, but then I have to pay to find out... "Oh... THERE WAS PHYSICAL AND SEXUAL ABUSE TOO AND HOW MANY OF THEM DIED OR WENT 'MISSING!?' WHAT THE FUUU-"
Then again, we at least did go over the internment of Japanese Canadians (as mentioned before), and general racism toward Asians, especially out west, so I guess that is a bit of a start... A BIT! As we expanded and many Chinese immigrants were given an ungodly tax for moving, were given all the dangerous jobs building the railroad and 4,000 of them died in the construction.
Like I can admit the short-comings of the Canadian education system, but hearing stories in the US like teachers refusing to teach actual "Science," this blind Patriotism at times, or the mentioned issues around the South's telling of the "Civil War," it is just a complete mind-fuck from a Canadian looking at it.
