I literally haven't seen that come up. My eyes have been opened about this "Canadians are so nice" thing though. Total bullshit.
Edit: The fact that you bring up Russians out of the blue like this on Lemmy is interesting for me personally too because my go-to example, on this topic, of what I wouldn't do is wish ill on the Russian people as a whole because of Putin's misdeeds. The reason it is my go-to example is that I know Putin has a lot of public support there.
It will never be okay to wish death and despair on large groups of innocent people because of what oligarchs do. It just makes you seem like a thoughtless and heartless bigoted piece of shit if you do it.
