i disagree with this take because i think the US is largely regional with differences also in major metropolitan areas. like, indiana and ohio are not two different countries. indiana is a worlds away from california, though. fundamental point i agree with however
I think what most Europeans fail to understand is that the US is... really big. It's essentially 50 countries lumped into one, each with its own culture.
Football/soccer culture isn't the same in NYC as it is in LA, which isn't the same as Ohio or Texas, etc.
