Its all part of the clannish/wolfpack mentality of the animal sect known as humanity. We all have collective 'groups' that align by biology, sociology, and ideology. Its an ugly web. I'm either one of my family, one of my friends, a member of my county, state, country, race, ancestral root base, language, dress, religion, attitudes, age ... so many circles that partailly overlap ... and so few that overlap with enough of the circles to make me feel sympathetic comradeship with someone halfway around the world that has nothing in common with me other than age and sex. Such animosities are fairly pointless ... but were only at the footsteps of the modern age of communication and mass knowledge. We can't expect to shed several thousands of years of suspicion and xenophobia in a few generations. After all ... our great grandparents only had radio ... and the information and acceptance of others was nonexistant. Our grandparents saw the birth of television and the start of air travel ... but the small town mentality was still quite entrenched. Our parents were still born to a larval information age ... but grew up in the time of great strides and expansion in human education and general knowledge of their world. We are of the first generation to be born with a better grasp of human cultures than any that have come before. Knowledge no longer lies in the hands of a few intelligencia... but is there for pretty much anyone to just take at will. Our children will do better still... but the net effect of mass global acceptance and melded humanity will be at the expense of traditions and the little elements that make any of us unique from one another. Change is hard ... most people do not desire it. I for one do not like the endless mass global violence ... but a world one of one mind that no longer has any culture or values scares me just as much.
