Observe how some remain surprised, offended, and wearisome that blacks object to being killed by employees of the state. The fact that armed white mass murders are apprehended alive or that thousands of violent insurrectors can storm the U.S. Capitol and (with the exception of one) leave with their lives does not faze these people (Tucker Carlson, for example). They are tired of blacks insisting that their (our) lives matter, even as they continue to be killed.
These defenders of the status quo do not see blacks as being equal to them as humans. They insist that their need to feel safe is more important than the need of blacks to breathe. The contrast is clear.
It is a moral challenge.
