https://fee.org/articles/the-progressive-ideas-that-fueled-america-s-eugenics-movement/ Tremendous article from fee.org about how far left progressive ideas led to the rise of eugenics in America but as we know the Nazis in germany stole their ideas from the eugenicists in america and Britain and we know the horrors of that and the 262 million deaths that came as a result of pissing on human liberty for collective garbage and the fact we are still dealing with this crap via radical abortion policies it seems we have not learned our lessons about valuing human life and liberty but the good news is people are waking up to this and that is a good thing
