The white race is simply not endangered. There are lots and lots of white people. Xenophobic race segregation leads to declining genetic diversity, inbreeding, social pigeonholing and an eventual evolutionary dead end like the Neanderthals. However, adaptive species that continue to evolve become powerful and long-lived mainstream entities. "Races" are just the internal variations within a species. It is quite impossible to prevent them from evolving, branching out and either dying off or continuing to evolve. You can't just say, "This particular race at this point in evolution must be preserved just like this". It's a recipe for extinction.
The White Race has done quite well with a very minimum of race mixing. If diversity is such a good thing then surely race mixing should be avoided. As time passes, the U.S. is looking more like the Brazil of the North. I simply cannot believe that that is a good thing. Among civilized individuals, a peaceful coexistence is sufficient. tgsam
You don't understand genetic diversity then. I wasn't speaking of social diversity. I don't see what is particularly bad about Brazil.
I not only understand genetic diversity, I also understand what my senses and common sense tell me. I find Celts, Nordics, Anglos, Saxons, Franks and other Europeans much more attractive than most Brazilians. tgsam.
