One of the major differences between old eugenics and new eugenics:
* the possibility of genetic engineering, not just breeding
* the ability to control fertility without surgery (injectables), thus sterilizing people without explicitly doing such, AKA you never get permission for a baby
* genetic testing to weed out the unborn is more palatable than killing those you can see
This was foretold in Huxley’s “Brave New World”. We can do this now and a lot of Libs would like to play God.
