I wasn't saying that racism or divisiveness aren't present in the US. I am absolutely with you on that, both of those things are present in the US to one degree or another, depending on where you live in.

I was simply saying that a significant number of people in the US get so myopically focused on those issues locally, they don't realize that there is a whole world out there, where those same issues are massively more rampant and ubiquitous. And when they suddenly discover that through a first-hand or a second-hand experience, it is understandable they would be shocked.
