Let’s look at the water glass as if it was half-full.
Maybe the continued use of abortions among self-proclaimed more ‘progressive’ members of society will result in a cleansing of the gene pool of the recessive ‘progressive’ gene.
Actually, we have had the use of abortion as birth control for a long enough period of time to start to see an effect on the gene pool. Since women who have abortions are less likely to have children (both because of psychological factors and physical damage preventing future live births), they *are* weeding their genes out of the gene pool. A weak maternal instinct is almost certainly the product of genetics; it is just one trait that is being bred out through abortion.
OTOH, it is still a brutal and horrible experience for those babies who are being killed, no matter what their genetics are.
