This has always been a thing.

The joke when I was you was "how can you tell a Canadian from an American travelling abroad? The Canadian only has one flag on their backpack."

It used to be a cross we would bear, but if I see it in the wild now, I'll probably get a knife and cut it off.

Fuck 'em. Yes, even the left-leaning, trying-to-fix-things Americans. Fuck 'em all.
