Sorry, not at all how I meant that. It's being told not to have children that is scary and gives me the ick.
I don't want the world to get to a point where no one wants to have kids anymore. I recognize that a lot of things happening now make it really hard to stay optimistic, but we — humanity — are the only ones who can do anything to change it for the better. And given the choice between "we might as well give up and just die out as soon as possible" and "we need to do everything we can to give the next generation the best chance of surviving and thriving we can", I'll always choose the latter

Maybe I am, because no one's given me a better explanation of it than "having kids bad"
Just pulling straight from Wikipedia, "Antinatalism or anti-natalism is the philosophical value judgment that procreation is unethical or unjustifiable" and I can't see how that doesn't lead to the conclusion that the planet is better off with humans being extinct.
Every argument I've heard boils down to "it's easier just to die than to fix the problems that make life miserable, so we should all just die." If you want to give up, go ahead. I personally don't want to ever have kids, but I still want the world to be better for those who do.
