Your theory- that men are disposable because theoretically it requires only one man to fertilise however many women, is flawed. One of the most ancient human concepts is that of marriage- mating once and for life is found even in the animal world. Marriage easily predates war.

I didnt said men can die winhout harm to the species, I said that if a large amount of population has to die because of, lets say, a war for survival, its better that it be men so population can be replaced faster and the war is less likely to be lost.

And the concept of marriage is ancient because, like I said, then our culture was formed there wasnt the need of such mass sacrifice, society wasnt organized enough for a war against a said enemy to be organized, so there was a even amount of men and women. But even so marriage as we know it wasnt present in ever culture, in some ancient civilizations it was common for most men to have no wifes while the richer ones had several.

But after some of the largest known conflicts ww1 and 2, there were very few illegitamate children; even fewer than in later more peaceful times. There are some cultures where men have multiple wives, true, but not for the reasons you describe.

This is not really correct, actually. I can't speak for legitimacy or illegitimacy, but I can tell you that the fastest periods of population growth (in europe and the USA) in modern history were immediately following WWI and WWII. But this is a different matter -- high mortality rates strongly predict high fertility (not biological fertility, but demographic fertility).

Instincts dont work through clear though, they work on the emotions.

what???:perplexed:

You dont know the reason why you should do it but you fell you should anyway.

decisions can, and get, emotional values attached to then.

Avatar -- I agree with you; except that there were an estimated 10 million rapes committed by the Red Army as they surged through Eastern Europe in the last year of the war; and the occupying Japanese armies in Mainland China and Korea raped millions of women as well. But yes, the "baby boom" after the war was mostly couples.
