This is a pretty interesting read. The author says that when all men in a nation act like PUAs (devoted to picking up women and having casual sex rather than marrying one woman and being monagamous), this course those monogamous genes to be bred out of the population, and then the country can never recover.
The author is using the term “co-alpha” the way that most people around here use the word beta. Beta behavior is being nice to women providing for them. Alpha behavior is having many sexual conquests and giving nothing back to the women. And I agree that beta genes can be bred out of a population very quickly if the population abandons monogamous marriage, because in the absence of monogamous marriage, what happens is that 20% of the men have 80% of the sex, so all of the good beta genes get removed from the gene pool pretty quickly. This is why the greatest danger to the future of the United States, besides the preponderance of people with low-IQ genes, is the trend away from monogamous marriage.
This is also a reason why libertarianism isn't the answer. The libertarian would say it's not the government's business to support monogamous marriage.

This post isn't really about the thousand or so people (out of a population of hundreds of millions) who read game blogs and try to become PUAs, but rather about the general decline from a society based on monogamous marriage to one based on men who have sex with many women, and when these aren't high IQ betas pretending to be alphas but real alphas, they don't practice safe sex and the result is babies.
