Blacks have not kept up with other populations in the U.S., presumably largely due to abortion.
They have been losing ground to Hispanics and other groups.
When Margaret Sanger started the population control movement, one of her primary interests was exterminating blacks and other races that she considered “inferior.”
At the same time, however, 3 out of 4 babies that are born to blacks are illegitimate. That in itself is a crime and irrefutable proof of the moral bankruptcy of the race. There was a time when having a baby out of wedlock carried a stigma. Nowadays, especially among blacks and hispanics it has become almost expected.
