Some people want to believe that today's world can be prejudice free. But the reason why today's world is the way it is, is because of children. They learn what their parents believe in as far as values and prejudices. When these children grow up this prejudice turns into hatred and this hatred is what causes such things as Columbine or the ethnic cleansing in Yugoslavia. If a parent is prejudiced then the children will learn from them and grow up that way.
Children also pick up on the media, teachers, and famous people's beliefs.
The way to create a future where prejudicial beliefs are not found is to educate the children. Adults aren't going to change their views easily and without a fight, but children will. Most adults are prejudiced because their parents were, and their parents were, and so forth up the line. History repeats itself. People don't believe that what happened or happens to other races or religions could happen to them.
