I suggest this is what happens when DNA combines with other DNA, which is only natural. Too much inbreeding in any group causes defects. The world is becoming multicultural because there has been far too much inbreeding in all the races. Europe and America are leading the multicultural edge, but in the next 100 years or so, probably everyone will be multicultural and multiracial. The Multis are the future. It’s not genocide, it’s evolution. Surely, you didn’t think the races would stay the same forever? Nothing does. Everything changes eventually. All the distinct races are dying out. It’s just nature.
