@chriscoreline Great, but a) I am disabled and generally cannot read whole books, and b) I *am* already learning about the basic issues but those crucially do not answer the *very specific* question that I asked in the original post, and like I mentioned, this is a problem *now* and perpetually waiting for the answer to magically coalesce is not really an option.

This whole discussion is kind of moot anyway, because the question was already answered - by a white person, I might add, whom I trust to derive their explanations from what non-white folks have said, as the post asked for - and so I have the answer I was looking for now.
