I've been reading about this theory lately and I wonder how do you explain the fact that:
People generally are in so much harmony with life on this planet with its ups and downs.
They look down upon ideas like antinatalism, calling those who embrace such philosophical positions as depressed/negative, etc..
People are reproducing like rabbits, grateful their parents brought them here and want to live forever. And I am not talking about a minority of rich people or something, I am talking about the average extrovert who also normally struggles, facing hardships, etc but they know how to adapt. Even grandparents who lived long enough and seen enough still viewing happiness as making a big family, and wishing/advising those around them to do so. It's easy to tell they belong here.
