“Black Lives Matter.” What is implied by this statement.

Perhaps we can think about the phrase “Black Lives Matter.” What is implied by this statement, a statement that should be obviously true, but apparently is not? If black lives do not matter, then they are not really regarded as lives, since a life is supposed to matter. So what we see is that some lives matter more than others, that some lives matter so much that they need to be protected at all costs, and that other lives matter less, or not at all.
