“If the differences between women and men begin to blur, society’s ‘sameness taboo’ goes into action. […] At a rock and roll dance at West point in 1976, the year women were admitted to the prestigious military academy for the first time, the school’s administrators ‘were reportedly perturbed by the sight of mirror-image couples dancing in short hair and dress gray trouser,’ and a rule was established that women cadets could dance at these events only if they wore skirts. […] Women recruits in the U.S. Marine Corps are required to wear makeup—at a minimum, lipstick and eye shadow—and they have to take classes in makeup, hair care, poise, and etiquette. This feminization is part of a deliberate policy of making them clearly distinguishable from men Marines.”
