I think there's a very sensitive and subtle problem with the whole issue. I'll try to be as subtle and as gentle as I can in describing it in the hopes of not being misunderstood.
What distinguishes moral judgement from, let's call it legal policy or law, is that one of these two is forcefully implemented in order to make people act a certain way with punishment being forced upon the disobedient. Antinatalism, for me at least, is fascinating because it touches on a binary choice where both choices do not carry any drastic legal consequences while still retaining massive moral, existential, social, and economic implications on a large scale. It's what determines whether the human species will continue propagating towards the future or not, and whether that propagation is justified given the suffering it leaves in its wake. That is the undeniable issue that lies at the core of antinatalism.
The gist of what I'm trying to say is that moral choices that do not carry drastic legal implications (although they are a very small category of choices, like whether your diet is vegan or not, whether you'll reproduce or not, whether you'll adopt or donate, how much you should donate to the poor, whether you'll commit suicide given you might make loved ones suffer, whether voluntary euthanasia should be allowed to all which it absolutely should be, whether you should divorce if you have kids, whether you should commit suicide if you want to but you have kids who still depend on you, stuff like that) aren't universal, absolute or, most importantly, oppressive (except for the one about legalizing euthanasia since, if you can spot that, it's the only choice involving drastic legal consequences and hence is oppressive to us prochoicers. Apart from divorce where the law only acts as an instrument and does not influence the personal choice itself, same with adoption). They are subjective choices and they cannot be generalized or implemented in a practical manner due to their sheer logistical complexity and impracticality. We are all very divided on these matters, that's where this complexity stems from. It's unfathomably weird how much our opinions differ in these matters.
Antinatalism absolutely does not force its choices on other people, it only demands that people should view and evaluate life through the lens of negative ethics and it has arguments that support that. That's different from saying that antinatalism forces people to refrain from procreating, that's absolutely false. It only demands that you judge reproduction as unethical given some particular set of claims and arguments which you might not accept, which is totally fine since these claims aren't absolute. But, my view in antinatalism is unwavering since I personally can't find any arguments that are capable of leaving so much as a dent, but again that's my opinion. And an opinion that is used to justify moral choices like the ones we're currently dealing with don't warrant or justify punishing people who don't agree with it. Antinatalism or any moral philosophical position for that matter is absolutely not as mechanistic as crime and punishment. We're not In a fucking court is what I'm trying to say lol.
In the end, antinatalism forces you to take a specific view of morality - a negative utilitarian one. This makes a huge difference from claiming that antinatalism forces you to refrain from procreation. It does not do that, it demands that you view the act of procreating itself as unethical. That's why some ignorant people claim that antinatalists are eugenicists or something. Eugenicists aren't interested in morality, they want a super breed of humans through a process that involves forced sterilization legislated by the law and selective breeding of those who are determined to be fit by standards that whatever nazi-like government set up. Arriving at a decision through the discussion of morality is what characterizes a lot of the philosophical discourse around these ethics topics. That's way different from being oppressed by choices that influence the laws which guide and restrict our actions.
And what if Antinatalism actually claims that you should refrain from procreating directly, it does not demand that those who reproduce be punished. In fact it can't, because antinatalism is negative utilitarian. It is anti suffering by definition, so it will just force you to minimize the suffering of your offspring. Why can't people see how delicate, empathetic, and forgiving antinatalism is lol.
