What do you think of cousin marriages ?

I did say "misinformed or not". I have though met few Chechens. Incredibly impressive and imposing men.

YOu are quoting a cracker from NC . Really ? That also in the face of facts for British Pakistanis. If this is not twilight zone, nothing is.
yes i should not quote professor Alan Bittles who is director for the centre for human genetics in Perth, Australia and have done many years of research on this subject and by the way genetic screening test can be done to clear your doubts if you are opting for cousin marriage

All Humans are related
Marriages between first cousins are not so common in our society, but chances are high in many closed societies and tight knit communities that a spouse is a 6th, 7th, or 8th cousin, at least. Scientifically, inbreeding refers to procreation between much closer relatives. If you follow your pedigree backward in time something interesting happens. You had four grandparents, and eight great-grandparents, right? Go back an additional generation and the number of distinct ancestors should be sixteen; still probably true for most of us. Now, project backward eight, nine, ten generations, and the predicted number of forefathers and foremothers comes out to 256, 512, and 1,024, respectively.

But you really don't have that many ancestors, because your pedigree contains 'repeat ancestors', people who are your foremothers or forefathers—as well as fore great uncles and aunts multiple times. The number of repeats increases the further in time you look back, such that your total number of ancestors is hardly increasing once you start looking more than 12 generations or so into the past.

This phenomenon is called pedigree collapse and it makes sense, because without it the human population in the past would have to have been larger than the 7.34 billion that it is today--a lot larger. Yet we know that it was a lot smaller.

From archaeology and from studies of Y chromosomal and mitochondrial DNA (mtDNA) haplotypes, we know that human ancestors went through several genetic bottleneck and founder events, in which small groups of individuals gave rise to populations that expanded into different regions of the globe. For this reason, human genetic diversity (the amount of variation in the human 'gene pool') is notably less compared with genetic diversity within various non-human primate species. The relatively low amount of diversity goes hand and hand with inbreeding which reduces diversity. To account for the human pedigree, the further back in time you go, the more breeding there had to be among people sharing great-grandparents, grandparents, great-uncles and great-aunts, uncles, aunts, and even parents. Incest may not sway with our current cultural beliefs and practices, but it most certainly happened. And none of us would be here today without it.
