When we have blacks blaming whites for problems they themselves have caused, we have every right to speak up rather than accept blame for something we are not guilty of.
Here’s an analogy:
My neighbor painted her living room while she was drunk, and she made a mess. Instead of admitting she was irresponsible, she turns around and blames me - saying I was running the dishwasher and it made vibrations and that it’s MY fault her living room looks like a 5-year-old painted it.
So I say that painting while drunk creates problems, and then she, with an air of righteous indignation, says “how dare you tell me why my living room looks so bad!”
If she hadn’t blamed ME for her own bad choice - painting while drunk - it would not be necessary for me to point out where she went wrong.
