It took me a really long time to read the book. According to Goodreads, I started in February 2018 and it wasn't finished until April 2021. The book was boring, repetitive and, at least in English, too difficult for me to understand.
People usually don't stop to think about whether it is morally and ethically right to have children. If only the child's best interests were thought of, reproduction would always be skipped. Parents try to protect their child from all suffering, but the only way to ensure the lack of suffering is to never exist. So people are not really interested in what is best for a child.
By bringing a living being into this world, parents are responsible for all the suffering their child experiences in life.
Voluntarily childless people are still frowned upon in society. Antinatalism is not about not liking children. On the contrary, we try to prevent possible children from suffering.
As you know, life is a deadly venereal disease. I could never condemn anyone to death, especially my own child. Hence "voluntary" infertility.
