Racial segregation is one of mankind's worst creations. How is it even conceivable to discriminate someone because they were born in a different part of the world and their skin has a different amount of melanin in it than yours. These learned behaviors are what will make certain cultures obsolete.

When you put young children together, from a number of different backgrounds, they have no idea what racism or prejudice is, they simply play together. Racism is a learned behavior and I am amazed at how poorly we sometimes treat each other based on nothing but our skin pigment
