Antinatalism 2.

Since we already exist and we are conscious about it, we are forced to either try to bring others to existence or not. You say we force others to exist, and I say you want to force others to not exist. Again, we can't ask someone who doesn't exist if he/she wants to exist, as the reply would imply existence in some form. We need other criteria.

You say we risk bringing someone to life who may have a shitty life, and I say we risk not bringing someone to life who may have an awesome life.

You made a counter-example with 2 lives, a good one vs bad one, neutralizing each other. And I countered it with a gradient, affected by variables like knowledge, technology, resources, education, etc. We can increase the likelihood to have more humans with good lives than humans with bad lives.

Now you say that one single bad life would be enough. I say this is a claim, not an argument. But maybe you consider it an axiom: suffering outclasses any amount of pleasure => suffering should be avoided at all costs.

In that case, what's left is to make questions to test the consistency of your axiom and try to lead you to a contradiction or double standard, but I think we should leave it here because you know more or less what I would ask and I know more or less what you would answer. However, if someone asked me... I would accept falling in the wronged group. If we could optimize our context to a 85 % ratio, being in the 15 % for me is worth it because of all the humans who had great lives. Despite all the suffering in my own, absolute garbage infancy, etc.

Regarding the human history of violence and wars, it has already happened and we can't do anything about it. What matters is what we can do from now on. And even if there were 300000 years of violence and war, in the future there could be millions of years of pacific generations who have great lives on average, or at the very least decent ones. What we know is that non justified violence (like non self-defense violence) isn't a rigid condition in humans. It's about the variables that affect its probability and we can manipulate to some degree, despite not having a total control. In the same way we can manipulate the variables that affect a child. And if we can't in a particular context, then the concrete humans in that context are the ones who shouldn't have kids. Not the entire humanity.
