Interesting take.
The things we thought were forced underground appear not to have been buried to deep after all. And while it is notable to recognize "strides" made in a nations' history, those achievements are still against a backdrop of the genocide of Native Americans and the enslavement of Africans to build it. So nearly wiping a people out, and making chattel out of another, seems to make having a place at their lunch counters and stores insignificant in hindsight.
When you said "one of these shooting cases was a small female police(woman) faced with a large seemingly out of control African American male," what case were you referring to? Definitely not Tulsa, because Mr. Crutcher was hardly "out of control," he was in fact in a great position to be subdued without violence. The notion that this female was terrified is hollow, she was allegedly a trained cop, so she was no shrinking violet, and she was surrounded by several of her peers for back-up, including one who was her husband in the helicopter. So where in the video do you see "out-of-control? I understand how white perceptions of blacks through western media conditions how people abroad see us, so is it possible that he appears out of control just because he was big and black. So what case were you referring to?
