Since the pro-abortion lobbies are predominantly white and the number of abortions is disproportionately black, the racist argument cuts the other way. What is happening is white Progressives are arranging for the killing of Black babies. The original head of Planned Parenthood, Margaret Sanger, was a big advocate of using abortion as a tool for eugenics.
I’m for Roe v Wade, but I don’t see how you can say opposition to abortion is predicated on racism given the racist origins of the abortion movement and given that many Black Americans are staunchly pro-Life. The truth is abortion is an issue that cuts across race.
