A very good idea. As you say, however, it is unlikely, but its improbability doesn't mean we should give up on it. Change comes, sometimes quickly, sometimes slowly. Even though the problem may seem an insurmountable task, the best way to eat an elephant is one bite at a time. So, let's at least nibble.

Though I mostly agree with you, I have a slightly different perspective on the slogan "Black Lives Matter" and its appropriate use. Sure, Black lives matter, but those lives matter no more than nor less than the lives of any other folks. I understand the belief that some folks feel the need to foreground that, but I also believe that they are wrong.

I am a mostly European American, that is, most of my ancestors (for the past few hundred years) came to America from Europe, specifically from Ireland, Scotland, England, Denmark, The Netherlands, or Germany, or they were descendants of folks who came from those countries. (We shall ignore the tiny amount of Native American/First Nations DNA I carry.) I am also a democratic socialist much like my hero Bernie Sanders. So I have both "White" and "Leftist" tendencies. No, that's not right. I am White and Leftist, no tendencies about it.

Even so, I am offended by other White and Leftist people who repeat "Black Lives Matter" in chorus with Black folks just because they want to prove in some pathetic little way that they are in solidarity with Black folks, that they care. They may well be in solidarity, may well care, but people who have to raise their hands and shout, "I am sensitive to the issues that Black folks have!" probably aren't as much so as they think they are. They may be well-intentioned, but they are sloppy in their thinking and acting. They are seeking simply to assuage their own consciences, seeking to plug the hole in their social dykes caused by Liberal White Guilt. It is one thing to think and act in a way that recognizes the humanity of anyone, and another to raise one's hand or voice to draw attention to oneself doing so.

I say, "All Lives Matter" without any sense of privilege or guilt, without any apologies, and I doubt that I shall ever say, "Black Lives Matter." All lives matter. Let's work for a society, a country, a world where the humanity of every single person is celebrated and defended.
