OP here, yes that's the whole point, I'm attuned to the differences. There are two/three countries that I could say I'm fairly attuned to the difference, Sweden (native), the US (lived there for 6 years and we brought up on American culture) and _maybe_ China. In my experience, Sweden is more diverse in terms of dialects, architecture maybe similar, while the US has more natural diversity (obviously) and food. In terms of cultural diversity, both are quite homogeneous in the mainstream white population, and both countries have a large immigrant population, but Sweden's is more recent (30% of Swedes have a foreign background), but the US obviously have a big black population that goes way back. On the other hand, I'm not very attuned to the differences within e.g. Norway, the UK or Spain, but based on the politics that is visible to me, there are quite stark differences in many European countries and I have no reason to believe they are less diverse than Sweden or the US. You can debate which are more or less diverse, but you have to admit that they are on the same order of magnitude. The difference between European countries is an order of magnitude or more different that the differences within the US. I can't understand how anyone can argue otherwise.
