Have ya'll ever met eugenicists and racists? those are some of the most natalist motherfuckers out there. You think all the mystic woo woo "having children is like +1 good" bullshit you want, THOSE PEOPLE THINK THAT HARDER THAN YOU DO!!!
This rant is sponsored by yesterday's grandma demanding in the form of a question when I'm going to shit out babies for her and also random strawman comments in an obscure subreddit.
Edit: ITT: people actually starting to bully me for not wanting to have kids. Did not expect this on "leftist" website.
Antinatalism is nonsensical edgy thrashing at best, and Malthusian at worst. It's usually the thrashing, but it's presence on the modern internet has clearly been guided and platformed by the latter. Building socialism as a method of reducing birthrate is a generous redirection, but the core concept of antinatalism is always purely individual and irredeemable as you've stated.
