People almost always fear the unknown, which is what a large portion of prejudice starts with, it is a lack of understanding of what is different than themselves. Unfortunately while it may have stemmed from that, it has now been passed on to generations. Children are not born prejudiced, it is a learned attitude and behavior. Recent sciences show that we are all descended from the same original pairing so the theory that we are different doesn’t really hold up. We’re all a part of a race of humans.
