Plato was right.
The biggest proponents for antinatalism I know are educated upper middle class childfree whites who rattle off about it to other educated upper middle class childfree whites. Antinatalism is a privileged position I agree because only the privileged have the emotional free time to ruminate about the "suffering" inherent to existence regardless of socioeconomic conditions.tldr: don’t trust whatever lazy trends white people be pushing (Because this is some white people thinking so they can go back to sterilizing non-Whites)
However antinatalism is not eugenicist. It is nihilist (think Thanos.) That is the obvious argument against it and that it tends to be championed by the depressed and mentally unwell. Comfortable depressed people think it is a problem with existence itself, not their conditions. It follows they would advocate against all human existence.
For all the arguments that antinatalism is anti-black, I would say that is a product of the fact that most antinatalists are not black and so that person with an "air of superiority" is also white. Since all white people are at least passively racist, it is very disconcerting. They're just your garden variety "raceblind, don't think about black people or our issues at all" racist instead.
