Lets deconstruct, shall we?
If All Lives Matter signals that black lives do not matter, then black lives are not included in the set all lives. If all equals every life, it means that blacks are not part of life.
How can this even make any sense, even to the handful of Stone cold anti-black racists who might exist?
The only logic is to include any color skin of living people into the set of all lives. And proclaiming that any one color of skin of living people matters says that the others matter less or not at all. Thus all lives matter is a better slogan, which leaves no group of living people out.
I remember when the “All Lives Matter” reaction first emerged, the various organizers of “Black Lives Matter” just went wide-eyed nuts, obviously because “All Lives Matter” might dilute all those profits they knew were coming their way through fundraising and merchandising — though they tried to mask that by acting offended and angry.
The entire liberal population are such blatant fakes.
