Not all lives matter.
When someone in a nursing home has three co-morbidities and dies of the Cajuna Virus at age 88, it doesn't matter. Would have been dead within a few months anyway, taking a stack of large medical bills with them. George Floyd's death didn't matter. In fact, the world is a slightly better place without him in it. Pretending that it DID matter is nothing but a massive propaganda campaign, for no good purpose.
The domestic newspapers, especially in our large cities are largely populated with news items about Black people being slain on the streets, mainly in the course of other criminal activities. Occasionally, we learn that the deceased was an innocent who was "caught in the crossfire," in which case, maybe THAT life mattered, but not the others.
I'm at an age when I read the obituaries every day, and there are a lot of people that "no one has ever heard of," who did great things while they were alive. A lot of these people are People of Color, and it is edifying to see their impacts; those lives mattered.
But for most of us, including me, not so much.
To say that "Black lives matter" is racist. Whether a life matters or not is the product of factors having nothing to do with race...race is the least important thing.
