thats not true, world can run also without racism
As soon as you exercise differently, you are creating your own race.
racism comes from heuristics, rumors and experience,
Then there are 7.4 billion races in the world, because everybody experiences life a little differently than everybody else. But racism has to do with hostility with people of other races. Most people ignore the racism among the members of their family, neighbors, town, area. Some ignore the racism of their nation, other nations, and the world.
