Tyrants want you to actively express your sexual freedom, so that you will not notice when you lose your actual rights and liberties.
As political and economic freedom diminishes, sexual freedom tends compensatingly to increase. And the dictator … will do well to encourage that freedom. In conjunction with the freedom to daydream under the influence of dope and movies and the radio, it will help to reconcile his subjects to the servitude which is their fate. ~Julian Huxley, Preface “Brave New World”
