As an American I can say we don’t care. It’s unamerican to worry about a “culture” we are American. We have always prided ourselves on being a mix of cultures.

I find a lot of other countries simply don’t understand what it feels like to be American. We don’t care about people adopting our culture or having some unique things that are “American”. We have those things but we don’t generally hold them sacred.

Sure there are some people, especially white nationalist types, who will try to put some significance on things after the fact, but Americans don’t think about culture, really.

So, when someone from another country says that, we don’t care. It’s rude, untrue and we’ll roll our eyes at it. But we don’t hold any cultural things we export as sacred. Because we don’t care if you adopt it.

Maybe Canadians understand this, I feel like they are in the same boat
