Why are you so obsessed with tribals? It almost feels like the Communist fear mongering that used to go in the 1950s (started by McCarthy), except now its over who is a tribal, and who isn't. People have their views on things, and you cant change those things. In America, there is freedom of speech, and in a democracy, you should be able to think what you want. There is nothing wrong with thinking a little prejudicial (everyone is prejudice, really), just as long as you don't actually express it to anyone. Anyone can hold tribal views, it isn't only whites. My point is, you cant just end racism, it will always be there. Racism isn't exclusively a "white thing". It's like calling someone a friend, same thing as calling someone a monday. They're both derogatory words, and both have negative meanings toward a specific group of people.
