Evolutionary Perspective
Women's lives matter more than men's. Why? If women outnumber men, every woman can simultaneously have a "bun in the oven," so to speak. By contrast, if men outnumber women, it is not the case that every man can simultaneously find an oven for the bun he would like to bake.
Furthermore, however many men there might be, the best offspring will result if the best male specimens get access to all the ovens and the rest of the male specimens don't. By "best" I mean the tallest, toughest, handsomest, most cunning, most industrious, most ambitious, and most confident. The rest of the male specimens are most productively employed as bodyguards for the women and the superior men, and in that endeavor perhaps to die.
Two additional principles emerge from the foregoing: (1) chivalry has an evolutionary basis (be ever so kind as to die for the women, please); and (2) it is likewise true that sexual selectivity on the part of women has an evolutionary basis.
Satanic Perspective
Male:
Fuck evolution. Fuck chivalry (unless I happen to like how it feels). Fuck letting the Olympian super-geniuses have all the ovens for their buns (unless I happen to be uninterested in baking or unless I happen to be an Olympian super-genius).
Female:
Fuck all this oven nonsense (unless putting buns on the socioeconomic dinner table appeals to me). Fuck all this chivalry nonsense (unless I happen to like being the recipient of it). Fuck evolution's paradigm of who the best sperm donor is (unless I happen to like that paradigm).
The foregoing illustrates why Satanism and genuine Social Darwinism, otherwise known as eugenics, are not the same thing. Satanism is selfish individualism. Social Darwinism aka eugenics is not.
