That is a simple reality. You CANNOT *fully* understand the black American experience. That is (can't resist) an 'objective reality'. You can empathize, form mental behavioral models, interview millions of black Americans to formulate stochastic approximations. But they are all inherently limited.
Absolutely NOT - that is the OPPOSITE of what I am saying. I am the 'person of privilege here in the US - white, male, straight, Christian. Yet I speak strongly as an advocate for many in other groups. Yet I understand that for all of my advocacy and empathy there exists a fundamental limit.
