I believe ethnic cleansing is the answer !

@SW-User with the speed and lack of real understanding or knowledge of genetics , we are making the mutation of the genes , far worse , the more we strive to combat disease and illness , the more complex and dangerous and harmful the strain becomes .
As for stupidity, that is the biggest downfall of mankind the believe he will outwit Mother Nature .
Inter race births are the underlined reason for Growth in present and project deaths in the very young and those over 45 , compared to say 25 years ago , medical intervention and progression will slow down in the next 10 years , remember 87% of iner race births are in the 7 most developed countries , the rest will just strive to survive , but eventually the scales will balance , if not mankind will become a mutation to he’s own demise .
Interesting how all other mammals still thrive well from iner - breeding as you call it

@Wishingwellguy Where is the formal research on this? Send me a link. Because you saying it just like that just sounds like an opinion. One I do not agree with.

@SW-User look up and genetic medical paper ( outside the USA of cause ) regards to leukaemia , sickle cell , lupus disease , glucose disorders , especially mental health .

@Wishingwellguy No I'm not going on a wild goose chase. Give me the exact research you're quoting your conclusions from. I bet you don't have it because they do not exist.

@cashless I know, and just because diseases are being recognised now doesn't mean they did not exist before.

@SW-User my evidence lies at your feet , your need to defend yourself ( racial defence ) , look at why DNA. Is no longer used to extensively in crime investigation and in the courtroom , mutation of genetics

@Wishingwellguy your evidence gathered from where? How do we know the genetics are actually mutating and not new research showing things that were unknown before?

We are going in circles and you've not provided any real evidence of your beliefs. I cannot go on a wild goose chase searching for something.

So I disagree with you. To me, that smells of bigotry more than human preservation. Even within animals, inter species bred are stronger, even though pure bred command a higher price. That's just because people seem to have a thing for pure bred that could be considered prejudicial.
Not necessarily the best choice.
