Chads of the tribes got all the women while the lessor men slaved away and eventually the lesser man would get tired of that shit and would murder all the Chads and his sons while keeping his daughters and the other women for themselves and they would fuck until the tribe collapse and they're bastards split off and created new tribes and even then not every guy Got a Woman because the betas would fight and kill amongst themselves.
Sometimes jealous Chad's would kill other top men for more women but most of the time it was the betas doing the killing through poisoning Chad's food, killing him when he slept or just plain beta uprising.
And throughout history as civilization developed we used to have little Snippets where men knew what women were capable of and can do the kept them and check and to be forewarned about Chad.
Dad used to tell his kid that he was the man of the house while he was gone because Dad knew that once he walked out the door the mom or daughter would do something stupid like bring Chad's over because there's nobody to keep them accountable while he's away so the son had to be accountable.
Chad had to play secret agent and sneak through the house or get the girls somewhere alone because the brothers and the dad would kill his ass if they found him.
It's just now in this feminist empowered era that Chad can walk through the door and fuck a lady's daughter and then as he's walking out the door get a goodbye blowjob from her mom while he goes to pick up some money from his bitch that he's living with. A feminist Society is not natural and anybody trying to talk about nature and natural selection in a civilization is a retard.
