I found something similar of the shockingly unnecessary politeness that Canadians have, to the point that a US citizen might find it slightly creepy. Beneath the surface it's an oppressive circumstance for many, in Canada.
As a Canadian, I fully agree but will also say that it didn’t used to be like that.
Canadians held doors, helped each other, and apologized for being in the way because we had a deeply ingrained belief that everyone is equal. When every human being is equal to you, of course you would help, or point out TP on a shoe, or applaud their culture.
However, at some point in the last 20 years “Excuse me” has gone from “We both have an equal right to this space, and I had not noticed I took more than my fair share” to “I’m dirt, and not worthy of taking space at all”.
People who believe they are equal is perceived as “high and mighty”/ostracized, while people who believe they are dirt are welcomed as fellow commiserators to complain with.
Fair warning: I’ve lived in Canada my whole life, and have watched a lot of shifts that either break my heart or frustrate me.
