The poison of the doctrine of "equal rights for all"—it was Christianity that spread it most fundamentally. Out of the most secret nooks of bad instincts, Christianity has waged war unto death against all sense of respect and feeling of distance between man and man, that is to say, against the presupposition of every elevation, of every growth of culture; out of the ressentiment of the masses it forged its chief weapon against us, against all that is noble, high-minded on earth, against our happiness on earth. "Immortality" conceded to every Peter and Paul has so far been the greatest, the most malignant, attempt to assassinate noble humanity.

-Friedrich Nietzsche, The Antichrist, 43.
