Even without the existence of a "presumed purposeful Being" (why capitalise if it's presumed? Whatever) man is still the most important form of life that we know of.

There is no question that we live on a doomed planet. Not because of "polluters" but because of the nature of existence itself; our sun will die one day and it will take all life in the universe, so far as we know of, with it.

Humanity is literally the only chance life itself has to escape this event. We are the only species that has even come close to escaping the gravity well and reaching other celestial bodies. So long as we don't self-sabotage, there is every reason to believe that we will be able to seed life elsewhere in the universe before it's too late.

Anti-natalism is not just anti-human, it's anti-life. If it's adherents actually believed it, they would kill themselves immediately. But they don't. They never do because no one actually believes in anti-natalism; it is always a gambit to cut down perceived competition for finite resources (which aren't). It's a short term strategy that risks the continuation of life itself for the benefit of the anti-natalist and/or their kind.

Why does this site's resident anti-natalist preach what they do? From her own mouth it's because of resentment that parents get money from governments for the raising of the next generation (which she will benefit from) and she thinks thst money should pay for her own, personal, medical care (benefitting no one but her).

Every single time.
