@Romeo Fabulini,
Have you seen the ones on Fox News? And Bloomberg.
It's as if there is a competition to see who can imitate a chain saw best.
Whether your DNA, and mine, is faulty is not a question that science can answer. I'm not convinced science knows what DNA actually is outside of the sort of thing one might see in a Dulux colour card.
There is the possibility that the DNA of those men who can be aroused by ladies from exotic locations is faulty. Or, to put it more scientifically, whether endogamy or exogamy is a natural evolutionary outcome.
It is usually the case that inbreeding is said to cause certain problems but it might be that it causes extremes and the problems are emphasised at the expense of any benefits for various reasons. The Pharaohs mated with their sisters. Darwin was in a first cousin breeding hutch as were many in the pre-industrial period.
And there are exclusive blood lines in most aristocracies. As there are in the activity of animal breeders. The Cruft's winner set against the mongrels. The Derby winner and the mule.
There may be an advantage in a certain amount of idiocy if it comes with a certain amount of genius over a situation in which there is a general IQ of 100.
It's an interesting subject to an evolutionist. The trouble is that most evolutionists are evolutionists for the wrong reason. For a subjective reason rather than a scientific one.
So there is no agreed answer to your question and there will likely not be for some considerable period of time.
