Societal destruction is hard wired into the female psyche. I saw a program about it on the science channel. Over the millennia of natural selection, the females who welcomed the invaders and mated to produce offspring thereby had a more diverse gene pool, and produced more diverse offspring, increasing the probability of having some who would survive to adulthood and produce offspring. Hence the tendency for serial monogamy in the female, and hence the tendency to discard the current mate in favor of a new conquering hero. The social engineers are well aware of what they are doing. The 19th Amendment sealed the fate of the United States. It has been a slow death rattle for the country from 1920 forward.
