Not really unusually. I feel like people don't fundamentally understand how progressive the US actually is. Like I'd really like people to travel more often. That's not to say the US doesn't still have a LONG way to go, but often the US centric (and this is on a global) mindset is that we're somehow the only ones with social problems. In reality we're one of the few places where our social issues are called out and fought against and there's ongoing change. Most other developed nations don't have nearly the diversity and progressive movements present in the US (which really puts it into perspective how far we have to go globally).
The US is constantly in the news for having the conversations, but a lot of other countries don't. Most just have far more homogenous societies and bury any ethnic minority issues. Sexism is REALLY bad in Japan and South Korea along with racism (traveling while black is a real and incredibly uncomfortable thing). I went to Italy recently and even for a tourist attraction it's insane how little diversity I saw compared to normal towns and cities in the US. I mean granted the US has a much larger population than most countries, but it's crazy how bad it is in so many "developed" nations and beyond that how little anyone cares.
Normally I'd wholly agree with you on many of the aspects you're talking about here, but one thing you said stood out and kinda poisoned the entire discussion:
What do you mean by "little diversity" when you went abroad?
I mean, do you go to an african village and complain because of the lack of white people? Do you go to a latin-american town and complain for the lack of asian people?
The US has an impressive history of open borders and massive inmigrations, which combined with the slave population that was shipped there and got emancipated later made the melting pot that helped make your country into what it is now; expecting the same thing to happen in other countries, civilized or not, is simply being ignorant of history, theirs and yours.
For now, as someone who actually is from outside the US and has (what I hope) a neutral outlook on things, just appreciate that the "racism" you see abroad isn't the same racism you see in the US; they don't see black or white, they see either countrymate or outsider, with the only inbetween being the amount of money they have/bring to their country.
