Human beings are generally fearful of the unknown, the strange and the unusual. We rightfully warn our children to be aware of and avoid strangers. We place things of an unfamiliar nature in boxes labeled beware, dangerous, harmful or not to be trusted. Thus, a stranger is to be feared. This sets the stage for hatred. To a large degree, people of all ethnic groups tend to be xenophobic, very often without really recognizing it. Xenophobia causes fear, and sometimes fear naturally generates hatred.
