If noone is cultivating and passing on positive culture, it's not making the chances of reducing suffering any better is my point.

ETA: I am not, to be clear, trying to say that having children is, in itself, a morally/ethically good thing. Generally, it is neutral but may be otherwise depending on one's situation. Choosing whether or not to have children is a personal choice - what's right for one might not be for another. Declaring others morally/ethically wrong for having children is myopic and likely a result of projecting one's experience into others.

In addition, antinatalism is bordering on eco-fascism, which is not ok. It seems most commonly expressed to make one feel superior while not putting in effort to effect positive change, like anti-electoralism/accelerationism.
