Modern day America has a problem with racism.
But the problem is not that Americans are not against it. On the contrary, you’ll have a hard time finding anyone who won’t come out against racism, or at least who won’t vigorously deny being racist.
The problem is that we don’t understand racism enough to get past the outdated caricatures of what it is and how it works. Guess what, people? There’s a lot of diversity in racism.
