Men often work in large or small groups that haze members who think too highly of themselves compared to their actual value of the team. The social dynamic of a proper group of men require self improvement and do not allow men to rank up if they are stuck at a mental state of 18 years old. Women did not evolve a social structure to handle this because what women bring to the table is the ability to help men maintain their "hunting party". Woman are very valuable at 18 because they are very fertile, more likely to be a virgin who can bond properly to her man, and have empathy and energy enough to cook, clean and maintain a nice quality of life for men and the family that that man swore to provide for and protect. At 18, a woman has more energy. She can be stuck at 18 mentally and it will be ok because being able to hold onto that charisma and energy level as she gets up in years is beneficial. But, women in the USA are not aware of their actual roll in society because men have been bullied into shutting the fuck up. Now women run amuck and do and say whatever they want as if they are a man. While women and men are equals, they are equal differently, and the propaganda makes it hard for women to understand that.
