Birth control itself, often denounced as a violation of natural law, is nothing more or less than the facilitation of the process of weeding out the unfit, of preventing the birth of defectives or of those who will become defectives. So, in compliance with nature’s working plan, we must permit womanhood its full development before we can expect of it efficient motherhood. If we are to make racial progress, this development of womanhood must precede motherhood in every individual woman. Then and then only can the mother cease to be an incubator and be a mother indeed. Then only can she transmit to her sons and daughters the qualities which make strong individuals and, collectively, a strong race.
Ok, now it makes sense. Birth control is the sacrament of eugenics.
