people should stop accepting that all forms of eugenics is "bad" - it's become so morally loaded that people like you are afraid to bite the bullet. We should be ok with having discussions about whether avoiding bringing children into the world with greatly reduced quality of life (or even pain-filled existences) is something we should be doing even though it's "eugenics"

I actually think it's reasonable to accept terms as they are if their definition has a long history. If eugenics means a system of forced sterilization intended to unfairly prevent certain people from having kids, (and it has for over half a century) that's fine. I can come up with another term to refer to practices such as embryo screening and we can all agree that eugenics was a very bad thing and would be bad if we tried to bring it back in the future. What I object to is then using a very loaded term outside of that original context to smear people that are making very hard choices, like parents trying to conceive a healthy child
