I didn't mean that you would literally give back any children you have.
I meant that having a child unlike buying an item or investing in something is permanent. You can't take back the decision later. If your child tells you their life is miserable and asks you why you brought them into this world there is little you can do. The world surely isn't going to listen to the protests of your child and will insist on treating your child like they treated you.
Ik the urge to reproduce is strong but a child is not just an extension of you. It has feelings, emotions and a will that is separate from you too and can suffer independently from your suffering. Many people regret having children that suffer in life. Children that incels have are likely to suffer in life because of epigenetic stress from their parent's suffering.
Epigenetics is an emerging area of scientific research that shows how environmental influences—children’s experiences—actually affect the expression of their genes.

Once you bring a child into this world to suffer you cannot take back your decision.
