We're not talking about Genghis Khan, we're talking about some inner city ghetto loser in 21st century America.
r/K selection
There are at least two distinct mating strategies in humans. One where the man gets as many women pregnant as possible but invests little or no resources in any of them. The other is where a man gets one or only a few women pregnant and heavily invests time and resources into his offspring.
The first type of men, like Khan, take whatever others have, they rape and steal and burn. These men end up being the destroyers of civilization, the second type are the builders of civilization like the Roman patriarchs.
The Khan strategy is self-reinforcing because it is mainly used in unstable environments, and the Khan strategy also causes the chaotic environment to begin with.
The Roman strategy builds a stable environment where you may have fewer children, but more is invested in them and thus they become higher quality. Kind of like how the high quality Spartans could hold off the mob of the Persian armies.
At least they would have the money to support them.
Raging retards are breeding out of control and killing this world. The Khans of this world are a destabilizing influence and hold back the progress of civilization. Since civilization has spread around the world you can look and see that the men who support the family unit and take the Roman strategy are slowly winning the battle against the chaos of the Khans.
Eventually, people like the jackazz in the news article will either be such a small part of the population as to be insignificant, or their lines will die off completely. But maybe I'm wrong, maybe the Khans will out breed everyone else, in which case the human race has no future.
