If anything, the mgtow movement proves all too often the good genes risk getting weeded out due to inherently dysfunctional and unjust societies.

Being that China is often the root of influence for these conversations, I will use that country as an example. I've read how often people who were incompetent at their jobs in Chinese societies from a long time ago would take their own lives due to their shame. Women in ancient China who wanted to pursue scholarly endeavors had to do it in secret, meaning no kids. Women who were widowed in Chinese societies often became Buddhist Nuns. This lead to a dying out of the gene lines for intelligent and independent females.

Western scholars who major in Anthropology, Sociology, and Psychology have all found that during War, the brave and courageous are often weeded out first. Due to the younger age of these soldiers, their gene lines would die. Females from the West labeled as Witches back hundreds of years ago were often curious, independent, and intelligent humans who liked to discover new things that Nature had to offer them were of course crucified.

Society has progressed due to the great ideas of a few, and despite the idiocy of many. People often overlook the lessening of intelligence and courage as one of the core reasons of the collapse of societies. The board mods on this site have lost their nerves plenty a times as an example of this.
