You are entitled to your opinion and Trudeau to his, all I'm saying is that it's a bit callous to characterize a large number of people as "shallow" or buying into a meme (the thing about loving americanisms) on the same breath as claiming it's a quilt (the implication of which is that there are significant congregational, not-americanized bubbles).
One can also make negative remarks about Americans and their americanisms, there's no need to accuse subsets of other populations of doing things subsets of your own also do, as a crutch for a us-vs-them style of narrative. That's cherrypicking. In aggregate, people are more similar than they are different.
When I say torontonians got over differences, this is sort of what I mean: diversity isn't a driver of outrage narratives for us, just a fact of life.
