The whole problem is that we are animals and most of us like sex.
The lack of sex can even be harmful, because, among other things, the lack of sex can lead to frustration.
Another thing is our natural desire to have children. Most of us have these instincts, even if not everyone wants to admit it.
Having a loving partner and a child/children is something exciting for many.
If we did not have these instincts, our species would have become extinct long ago.
The same as other animal species.
The funny thing is that nowadays relatively many people try to consciously or subconsciously cultivate their instincts with pets.
Some people literally treat their cat/dog like a child.
Everyone must understand that we are animals and nature "expects" us to reproduce.
The world may not have an objective meaning.
But from the perspective of nature, procreation, among other things, makes sense.
Of course, not everyone has to become a slave to the will of nature.
These are the reasons why, in my opinion, antinatalism is in a losing position in the current world.
Of course I don't insult people who don't want to have children (I don't have any either and I won't because I'll be dead hehehe), but I don't like how some people who call themselves anti-natalists insult people who want to have children. We should focus on having children responsibly. Not on insulting people for having children.
