You realize that "race" is largely a human construct right? Genetically, the differences between people of different skin colors isn't different enough to call them subspecies let alone different species. That being said, it is good that that hateful human construct is losing its importance. Ironically, everyone, including your hateful self, have benefited from the growth and prosperity that has come from freedom for all. Thankfully most white people or people of any color aren't as ignorant as you and realize that.
Yet, a person's race can easily be discovered via skeletal remains.
You ARE aware that the oldest skull ever found in North America was that of a WHITE woman? Do you understand that the discovery was quickly quashed by the 'Natives' who claimed the area the skull was found was a native burial ground, and should not be disturbed? Did you know they demanded the American government KEEP THE DISCOVERY QUIET? Why?
Growth and prosperity? There is more fighting than ever, especially internally. Crime is on the rise. All of this due to the differing races. Once Canada was discovered, and settled, only White people should have been allowed to settle it. I can guarantee Canada would be a far better country for it.
Allow me to ask of you a question. Why is it non-Whites immigrate to White homelands, but the opposite is never true? You DO realise the White race has been supporting the lesser races for centuries? The only reason countries like India and China have risen is because we ALLOWED it. White business saw a huge customer force, and decided to pull up the economies of both countries. More people = more customers.
