Fight patriarchy and fascism with your womb?
One of the non conservative/liberal criticisms I see against antinatalism is that good people need to have children, raise them with their ideology to make the world a better place because conservatives are having children. The idea is for "good people" to have children to outnumber the evil conservatives.
People often say this about the 4B movement's call not to give birth to a world that will discriminate against their gender. I saw a comment somewhere of a woman telling 4B antinatalists that they are going to be discriminated against whether they have children or not so they should have children to raise them to fight against patriarchy.
First of all, I personally don't care what happens to the world after I die. And if I am going to experience discrimination regardless, then I would rather stay childfree and enjoy my life as much as possible.
Secondly, anybody who has lived in oppressive systems knows that numbers alone are not enough to change systems: you need power (money, weapons, political access and control, etc.). If you do not have power, you and your future descendants are not changing shit. You are only bringing in more people to be exploited by the system.
All around the world, the ruling class are the minority of the population and yet the majority is unusually unable to overthrow them without power (money, weapons, political access and control, etc.). And even then the system of a few ruling class repeats itself again.
Thirdly, what guarantee do you have that your child as an adult will keep your ideology? Many people who were raised religious are no longer religious, women raised by working women are choosing to be tradwives, boys raised by feminist mothers turn out to be misogynists and even rapists. As minors, you may be the primary influence on your child but as they get older, you will not be. Adults choose their belief systems.
In conclusion, your weird cult like plan of raising children in your image and ideology is flawed because ideology is not hereditary.
