Sorry, didn’t mean to diminish diversity across Europe. The point I was trying to make is that the cultural difference between two extreme ends of the US is…well, extreme, and that you could find two regions of Europe, in different countries, that felt more similar. Not at all suggesting that if you pick two random locations in the US and in Europe that the US will be “more different.”

For example, the US state of Louisiana has about the same fraction of Louisiana-born residents as Switzerland has Swiss-born.
