Feeding the trolls again, btw the reason I am not still a member of this forum is remarks like Grab's above.Neither for or against Tribalism, what makes you think that?
Sure why not? If the primitve is hell bent on breeding it's kind toward Apedom why shouldn't they? In modern society the practice is controled, sadly what we have today, Islam , resticts the female not the male. A little biased lol.
In the USA, evidence is there but needs some analysis of data on crime, school performance and biography. Should the USA adopt Islam?. Something will have to be done - maybe not at this time but the day is comming, it not a question of whether but when.
A simple solution would be castration after the first population/crosspopulation takes place, the irrationality can be treated with either chemical or surgical tools. For example the frontal lobes of the brain could be removed in the worst cases.
Also not clearly stated - it is not alone the male lack of discipline that contributes to the trend but also the rapid pollution of a population by it's offspring, where typical statistics indicate up to 4 females to one male, ie he may have fathered 12 children for example - often in different states, so hard to document. Of these data suggests 6 will be male and the female inherits the damaged genetic material of further 'irrational' male offspring.
In contrast the monogamous population is being overtaken simply by being outnumbered, hence current estimates of 30% normal against 70% polluted.
Other areas of study - immigration, ie importing clean stock from mongamous societies Mexico being the current source as opposed to Africa where lots of good emigrants could be found lol.
22 million in the last 15 years - 10% adjustment lol.
