And maybe in the hunter gatherer days, men had the ability to part with unsatisfied women without much costs after the relationship becomes untenable due to partly, biological factors like the seven year itch. Now society actively punishes married men for the fact women have an inbuilt program to discard them after their kid is old enough to fend for themselves and mummy needs to look for better mate to get impregnated. Feminists insistence on blank slate theory when it comes to creating laws on family policies is partly due to the fact that if divorce laws were dictated by unPC rational science, there wouldn’t be such a power balance in divorce courts that benefits women as a whole.
