The fact that many women and men have made the childFREE choice proves your statement to be FALSE.All humans would love the experience of children, selflessly raising their own offspring, and their own extensions, caring for another person future as if it were their own, sounds pretty selfless to me.
It means that NOT all people "would love the experience of children," no matter how many times regressive kooks like you claim otherwise. No matter how much you whine about it, parenthood is OPTIONAL, not required. That means that a man or woman DOESN'T have to have children if he or she doesn't like or want them. Don't like it? Too bad. Other people's reproductive choices, including the choice NOT to reproduce, are NONE of your business.
