I will say one thing.
The Democratic narrative that the UK empire was drenched in blood and the support of most of the countries of the Commonwealth (former empire) for the monarchy are rather at odds.
For myself, I find the Democratic narrative rather like Star Wars. An attempt to cast history as the story of good versus evil. The United States is always good. The colonies were always evil.
Needless to say, that's a simplification. Even the American origin myth is a bit kooky, treating George III as advancing British policy in the American colonies when that policy was defined by the elected government of Britain. Small detail, maybe. I happen to be a supporter of American independence. But the American story doesn't begin with a revolution against a mad and despotic monarch. It was a rebellion against a parliamentary democracy, which failed to grant the colonies the representation it might have had in that parliament. But the fact that the US emerged determining its own future was a benign outcome, in my view. Although it might have chosen the Canadian way to do so as an alternative.
