Being nice and being empathetic are very different things. Niceties are protocol; you can be empathetic and considerate while displaying very different types of mannerisms.

Ok. Americans are nice, kind, empathetic, polite, and considerate.

Or is there more you want to quibble about on this topic?

I’ve found a good chunk of Americans to be vacuous, self centered and obsessed with performative individualism. Other people don’t need to make a show about their kindness.
