Eugenics of the Small Penis

Occasionally I hear that white males are responsible for all the world's problems and that they take an aggressive and selfish view towards other peoples and resources. I shall now advance my thesis on the Eugenics of the Small Penis. It has been shown that human life started in Africa. Given the generally accepted hierarchy of penis size, specifically Africans with the largest, followed by Caucasians and then Asians, the question becomes, “Why has large penis size been bred out of white and Asian males?”
Students of psychology note that many men with aggressive personalities are compensating for their lack of penis size. This causes me to think that for some reason Asian and white women over the eons accept a smaller penis, because the man with the aggressive personality provides them with advantage other than sexual satisfaction. In other words they would rather have someone putting more meat on the table instead of between their legs. Apparently African women have not made this compromise.
Why, then, are not Asian men guilty of destroying the planet? I think Asian men with small penises are probably as offensive as anyone. Geography plays against them as the Pacific is too large for them to make effective use of it for plunder. They do make a pretty good effort at assailing their own continent. I imagine Genghis Kahn is not packing much on his conquests. On the other hand the countries of Northern Europe are in good position to exploit the Atlantic for raiding starting with the Vikings. Danes are known for being big men with small penises and their forebears show history what compensation is. The Vikings rape their way through Europe spreading their genetic deficiencies and domineering mentality. The other European countries that become maritime powers simply refine and perfect Viking techniques and use the Atlantic as their highway to spoil.
It is hard to argue that white men have not been tough on the world, but I have shown that their women bear some of the blame by trading sexual satisfaction for wealth and prestige.
