Maybe I'm a weak antinatalist, but I think when it comes to having children it's just full of shit. Having a copy of "muh genes" isn't important. Forcing your own preconceptions of how life should be onto your little sperm golems is pure abuse.
Let's even leave ethics aside for a moment. If I wanted to have kids, it would be the desire to observe and assist a separate individual entirely. If I had a partner and she wouldn't want to go through childbirth, I would be totally happy for her. With all these, and the current state of the world, adoption sounds like the most rational choice.
Now, I'm not the one to be pushing my choice into anybody else, but I can't find any decent pro-birth arguments that aren't based on selfishness and misconceptions. When people go to claim stuff like this online, it sounds very narcissistic (me, me, look how virtuous I am for going through all these hardships), and with real life, it sounds unauthentic, as if it's just a peer pressure with a doze of self-delusion.
I read a story about a pro-life pair who went for an abortion because their unborn child was diagnosed with some untreatable condition (Down syndrome? I don't remember tbh) and they wanted him/her to have a good life, so they put their beliefs aside for a moment, despite how hard it was, and then made what I think was the right choice. That is the basis of antinatalism for me - the sympathy, the desire to see other happy that is stronger than your misconceptions.
I think I've said it few times, but being in denial isn't actually worse or better. It's suffering all the same, but being unaware, dumb about it.
