Well, the left has decided that White Lives don't Matter, and that it's "White Supremacy" if someone dares to say that (never mind that if we had REAL White Supremacy, "White Lives Matter" would be state-enforced!).
So the left can easily say that (White) Babies Cells don't matter, etc.
Apparently those same New York City Antifas were organizing out of a Brooklyn synagogue. (Sin-agog?)
