well, I'm not the smartest of people, and absolutely cannot engage in a deep discussion on this subject, but... We have no way to know how each individual experience in this world will turn out to be.
I personally have zero intention to bring a child into this world, since I don't think I'm exactly parent material, I don't want the responsability, but also beacause, there are LOTS of orphans kids around the wolrd, so to me it seems more reasonable, if I one day come to desire motherhood, to nurture a kid who was abandonned and is already alive. I also consider the state the world is in, I mean life has always been difficult, and of course, we can't predict if this potential individual will or will not enjoy existence, but the sole posibility of bringing someone to life for them to possibily experience the worst that this place has to offer... it's a no for me.
But then again, that's me. It applies to me because of my personal background, influenced by my personal shitty experiences in life. I do wish I was never birthed, I wish I did not exist, and to me, birth is a curse, existence is a prison, but that is my point of view. Yes, i think the world would be better out without us humans, but that doesn't give me a free pass to go around murdering people, forbiding them to have children and live the life they think is more suitable for them.
I want the freedom to call an end upon my life and at the same time I want other people to have a choice on whatever it is that they decide to do. It's not okay to impose our beliefs to people. Yes, i don't want children. No, I don't think humanity is worth of life. Yes, i think it be better if everyone decided not to procreate anymore. But that's a personal view, not an absolute truth. We have no right to assume that antinatalism is better than any other belief, as far as we know we can also be wrong. Just let people decide whatever it is that they want to do. Let people come to life, experience it and decide if they want it or not to continue.
+ Reproduction is kind of an evolutionary trait, i don't think it's realistic to expect that people won't wish for kids.
edit. I realized i made it sound like you guys wish to impose antinatalism, my bad, i dont think that's it, pls desconsider if i somehow was offensive and presumed something. i kind of got carried away :x
