(So "etymology is perhaps a bad term, but maybe what the word means can shed light on it's origin and social evolution), Why is there so much hate and violence in the world? A tired question, to be sure, but one worth continually seeking answers to, as we have never evolved past brutal violence and hate. Sociology points to the tendency for an "in-group" to assert dominance over an "out group," and the "out-group" revolts against the pressure and ostracism of the "in-group." It's an endless cycle of chest-beating, dominance, assertions of power, demands for recognition.
Some scholars think, it starts with OWNERSHIP and PRIVILEGE. It began with a notion that we own a certain land, a certain god, certain properties. It evolved with the notion that our kin, biologically linked, or socially linked, also owns and has distinct privilege of a certain material wealth. The idea begins, since everyone has this idea of privilege and ownership, that everyone else wants what "belongs to you." You must defend "it". THEY must defend "it." They are the out-group, you are the in-group. You are the in-group, they are the out-group.
What, would happen to us, as a race, without corporeal bodies? Without material possessions? Would our disembodied, intellectual forces find new ways of classification, dominance, terror, and discrimination? Is our species flawed to the spiritual core, or is it the physical manifestation of difference that gives shape to our hatred? What do you think? Can we evolve past hate, or is it tied intrinsically with physical being?
P.S. I don't have the answer, but it pains me.
