It's not so much assigning moral worth to potential people but attempting to stop potential people from experiencing suffering or imposing suffering on others. #antinatalism
That there is no objective morality, in my view, is a good argument for not bringing new life into existence. Why why new life into existence and expose it to moral nihilism?
Please, a few words on your precious ‘fur babies’ and pro-refugee outlook. After that it’s a short nap followed by fat acceptance and paint by numbers.
For antinatalists, this is the gold standard. Total extinction of all sentient life guarantees elimination of all suffering. There is a possibility life re-emerges through abiogenesis.
