Varg's comment on Polygamy:

If I may jump in here: I think having only monogamy will dig a deeper and deeper cleft between peoples of the same race, because the good guys get all the good girls, always, for generation after generation, but… the bad guys only get the bad girls, for generation after generation. So the good gets better, and the bad gets worse… we might get more divine on one side, but also… horribly stupid, ugly, coward and cruel on the other — all in the same society and because of monogamy.
On polygamy, I agree with you Mr. Talin: only the nobility/aristocracy had multiple wives/concubines, and this was indeed justified by nature itself. The good should get more children than the bad. And a good guy can perfectly well produce as many children as a dozen bad ones, if only he has enough wives and can afford it.
Today though, I think most men and women are unfamiliar with the idea, so to speak, and would not accept or appreciate polygamy. Yet they seem to think “serial monogamy” is perfectly okay…
Let’s raise our children to think differently.
