> Do the people downvoting this disagree that America has too much of a racism problem for a first world country, or what's going on here?

Unfortunately, that has been my experience. A lot of seemingly well-intentioned Americans refuse to accept their follies. They are completely unaware/unwilling to admit that the rest of the world is watching what's happening in America.

This is possibly due to the ingrained, "American exceptionalism" belief but I am willing to be proven wrong.

As a comparison, see this Brazilian admitting flaws in Brazil: https://news.ycombinator.com/item?id=17735229

But Americans admitting racism? Nope.
