I’m reminded of a joke, which I’m often reminded of when I think about this (excellent) point.

Two revolutionaries, one young and bright-eyed and the other old and grizzled, are sitting together. The older asks the younger what he fights for, to which the latter responds “For there to be no more rich people!” The older one sighs and says “How times have changed! Back in my day, we fought for there to be no more poor people.”

The point of this comment was not that men should be bought down, but that being asked to consider someone else feels like an imposition when you're not accustomed to doing that.

Are you saying that all lives matter?

No.

But I am saying that a black person should be able to get as good a legal counsel as a while person, among innumerable other things.
