Earlier quoted context omitted.
When writing this, did you consider that most African Americans are descended from people who didn't get to bring a suitcase? That they were still fighting to be treated as equal citizens a century and a half after no longer being considered property? And that the fact that they're over-represented in basketball doesn't mean that inequality is solved?
Note that you said descendants. They were not slaves, nor were their parents nor their grandparents. What remove does it take to get over it and stop acting like everyone owes you? Immigrants have come to America with nothing and having suffered unimaginable trauma (such as having had their entire family incinerated) and prospered.
If your bare minimum is "at least your family didn't get incinerated so get over it", that's extremely heartless and cruel: the US can and should do better than such a low baseline.
