I appreciate the way you lay out your argument but I refuse to agree because if you're right the consequences would be too much to grapple with.
Some abortions are justified, others aren't. A legislative compromise was done that lets unjustified abortions take place, enabling a loophole for eugenics.
If we embark in this eugenics journey, where does it stop? Should everyone with a GPA of less than 4.0 be killed? Should everyone not capable of running a marathon be killed? Should everyone with less than 1000 followers on TikTok be killed? Should everyone not able to name at least 100 Pokemons be killed? Should everyone with a chess ELO below 1000 be killed? Should everyone not able to solve a Rubik's cube be killed? Who defines what the minimum threshold to be worthy of life and reproduction is?
Eugenics is wrong and we should be able to say it. I've met people with Down syndrome who are formidable and inspire me to be a better person. People who have to wake up every morning and be resilient in an unforgiving world. And it makes me sick to think how many of them are being killed.
Steve Jobs was once a homeless person who consumed acid and ate charitable meals at Hare Krishna temples. A hard-line eugenics moron would have probably declared him unworthy of life or reproduction. Likewise, among the brilliant scientists and engineers that once put a man on the moon there are descendants of poor immigrants that arrived to America on boats infested with rodents, fleas and lice, many of whom had low IQ from malnourishment and exposure to pollution, and were also illiterate and unable to read. Eugenics is a stupid doctrine.
For anyone who is not religious, the entire process of procreation through to birth is life. There is no point at which life begins because every part of the process is life. If any part of the process wasn't life, it wouldn't work. Everything the parent said is correct.
