In the 1930s there was a eugenics movement. It hoped to eliminate genetic diseases and disabilities including mental retardation from the human race by sterilising people, sometimes without their consent. Hitler took up the idea and sterilised and also killed perfectly healthy people that he hated including Jews, gypsies and gays. This put any form of eugenics into disrepute.
In modern times, couples having trouble conceiving can resort to an expensive procedure called IVF (In Vitro Fertilisation). The church and Christian families pressure couples to have as many children as possible, so Christians are more likely to use IVF than atheists. The procedure creates perhaps a dozen fetuses then implanting the most promising ones in the womb. The rest are discarded. For some reason, Christians do not consider this abortion. This procedure can filter out some genetic diseases and can let you chose the sex of your child. Potentially it could let you produce a designer baby where you select any trait of your child you please. This is the modern form of eugenics.
Eugenics could be thought of as artificial selection piggybacked on natural selection in an attempt to control ultra-short-term evolution. Darwin never mentioned it. However, Christians tar Darwin’s name by falsely claiming he advocated Hitlerian eugenics.
Christians also like to falsely accuse all atheists of promoting Hitlerian eugenics. Atheists are just as horrified as anyone else. Christians also like to accuse atheists of promoting modern eugenics even though Christians use it more frequently than atheists do.~ Roedy (1948-02-04 age:69)
