I want to return to a previous post where I linked to and commented on a YouTube video of an 8th grader mercilessly documenting her best friend's libidinous ways, all while the friend begs her to stop and chases after her when that doesn't work. This is the familiar pattern of girls sabotaging their so-called sisters to get ahead.
Yet several commenters argued that the teaser was only acting under the influence of the patriarchal norms that she'd internalized -- if they were reared under a matriarchy, teenage girls would not act so savagely toward one another.
But let's get real.
This girl just so happens to police the sexuality of other females exactly at the time when she herself has a selfish motive to do so -- to keep them from competing with her for boys, from dragging down standards, and so on.
Think it through: if females policed others due to social brainwashing, it would show up in their behavior early on. Even by the end of elementary school, kids have absorbed most parts of culture that are not innate -- the ambient language, looking both ways before crossing the street, saying please and thank you, etc.
And yet elementary school girls don't harangue females of any age about their sexuality -- at all. They only start doing this after puberty.
Under the "social brainwashing" hypothesis, the perfect coincidence between policing and puberty is completely unaccounted for. Under the "advancing her own interests" hypothesis, it makes perfect sense. We conclude that girls tearing into other girls for acting slutty, once puberty begins, is as genetically pre-programmed as boys acting violently toward each other to attain top dog status.
