It is impossible to prove "race" as understood by retarded racists doesn't exist to them, because to their tiny minds every piece of scientific fact is jew lies, while on the other hand centuries old disproven notions are science to them, and the facts disproving them are again jew lies.
You know in those documentaries where they show primates learning 200 words as if it was a great thing, I think they should show racists on those programs. These people, despite having minds capable of only formulating the most primitive Aristotelean logic chains can stop at red lights, drink water without drowning, and even finish schools and get jobs, buy flowers to their girlfriends or wives. These should be shown not only in documentaries, but also in religious channels where they show some bugs and flowers and that way "prove the existence of god", they should show these weird organisms.
