Consider that in 40 years after 1968, there have been about 800,000 murders total in the U.S.. Since Roe v Wade in 1973, there have been over 53,000,000 U.S. abortions, over 66 times the number of murders.
And I think the 53,000,000 is just the tip of the iceberg when you consider all the babies that have died because of abortifacients.
