An editor of Playboy (I can't remember his name just now) did a history of the sexual revolution, and said none of this grand project in all its forms --- destruction of the marriage culture, rapid demand for abortion, the "sex work" prostitution-porn-trafficking revolution, mainstreaming of perversions, severing of sex from fertility, men from women, women from children, gender from anatomy, etc. --- would have been possible without, first, the Pill.
Not because of its effect on physiology per se, but because of its effect on minds and mores.
But at least the sex is great. (Cough, cough.) Right?
