All lives matter, of course they do. But saying that in response to “black lives matter” is, as I’ve heard someone say, like treating breast cancer or lung cancer by saying “all cancers matter.” The systematic murder of black people in this country must be stopped, and so attention must be called to it. Our systems don’t flesh out as though black lives matter at all, and so we have to say it. Saying it is, in itself, so scandalous, apparently, that it’s an act of subversion. Jesus would say it.
