I believe in a form of racial superiority. I believe mixed race people are better (generally) than pure breeds. I am myself quite pure bred. CMV

I've seen my family tree. We haven't been in Australia long, and so many of us came from Oxfordshire, and had been there for a long, long time. Our family tree tends to contain reasonably intelligent people (my great uncle was chief engineer on the first railway network in North Qld), but there's lots of schizophrenia, alcoholism and bowel cancer. We've got a bit of added Welsh, Irish and Scot...but nothing traceable from outside the United Kingdom.

Look at royal families breeding only within their own community. They end up a mess. I think this applies at a lower end of the spectrum if all your ancestors are very much the same ethnicity. Maybe not the same extent as super inbreeding royals, but to some extent.

My cousin is half Aborigine half English blood, and she and her brother are really successful, healthy, good-looking, sharp, stable people...much more so than most of the members of my extended family. And much more so than pure blood Aborigines tend to be. I hate to say it, because of the hateful history already involved, but if I'm being intellectually honest, I have to extent the same logic to Australian Aborigines, and posit that with the low population and geographic difficulty of Australia, that many of their communities past and present and pre-colonial were probably lacking genetic diversity too.

The most beautiful people I've ever seen are mixed race. Also many of the smartest that I've personally known. I have only met a couple of people in my life who I would say approach genius levels of intelligence and creativity, and he is my best friend from uni - half Japanese, half "White"...not sure which white.

Isn't the first rule of good genetics to spread the genes apart? Isn't the mongrel dog cleverer and brighter than the sleek but dopey pure-bred?

Additionally, I think making better humans is a moral imperative. HOWEVER, selection pressures and traits will always be too complex to predict and control. So the only answer is just to increase the chaos and the variety. Make a more diverse mix and let nature sort itself out. This will lead to stronger, healthier, smarter, more stable and better looking people. Eugenics doesn't work, because nature and evolution are too complicated to control. Increasing the variety and diversity however does work.

This is a refreshing change from all of the usual racial superiority cmv's. However the same issue they have applies here; all of your evidence is anecdotal or based on conjecture. Do you have any studies that show mixed race people are healthier/smarter/more attractive/more succesful?

In addition: Dogs are not people. Mongrel dogs are healthier than purebreeds because pure breeds have been artificially selected for hundreds of years for specific traits, and so genetic deficiencies were compounded.
