Abortion is the only thing the eugenics movement was able to achieve in societal change. There was discourse a few months ago surrounding some influencer couple who decided to abort their baby once they discovered it was gonna be born with down syndrome.
A few lefties were calling it eugenics while others were like "erm, ackshually bringing people in the world is le suffering, and specially if you bring a disabled kid to parents who dunno how to handle it, it'sgonna be more suffering for everyone involved!" So that makes it totally fine to kill the person, I just wish some people were actually honest about their principles and go full mask off.
