So after a couple pulls on the ol' Kahlua bottle I'll hit you with my Grand Theory of Why. Somebody way smarter than me probably came up with this before, but this is what I seem to observe.
The most basic traits that all people share are fear,and an innate, hardwired desire for order and meaning. Our brains simply can't wrap themselves around meaninglessness for very long. We need to connect the dots, straighten the lines, and join the curves. I don't think that's any great personality flaw, I think it's just the way we're built.
We're also terrified. Of everything.
Most prominently, we're terrified of the meaninglessness that our minds simply cannot comprehend. Our greatest fear seems to be that we're simply bags of meat on a ball of rock hurtling through space. After all, if that's true, then what's the point to anything? We need purpose. We need to be special. We need direction. We do not want to be on our own.
To make ourselves special, we look to things that we place on an order of magnitude higher than ourselves. Because our gods are superior to us, it gives us purpose, but also removes one level of responsibility from us, since we can always pass the buck upstairs to our supervisor. They put us here, because they have a plan for us. We need to do something. We're special.
So, in this quest for meaning and purpose, we attempt to communicate with each other. After all, if we can be heard, and possibly affect the life of another, haven't we done our part to create some meaning? So we yell, and we scream, and we print, and we post, and we sing, and we joke and we pray that it bounces back off of something in that void and comes back to us, because that will mean someone cares, and what we did meant something.
At some point, we don't even seem to care that we get negative reactions. We're so afraid of being irrelevant that ANY reaction is proof that we mean something.
And I think that's where things started to go off the rails. Communication has become so easy and so prevalent that it became ubiquitous. It's all background noise now. So in order to be recognized out of the void you have to yell louder than anyone else, and care less about the reaction.
It's an interesting aside to note that conspiracy nuts have been screaming for decades about a "surveillance society" where our every move is monitored and recorded. Well, guess what? We've got it. But "they" didn't do it to us, we practically demanded it. Now our every move is YouTubed, Twittered, Facebooked and blogged, and not so Big Brother can monitor us, but so we can hope somebody—anybody—sees us.
So, anyhoozle, that my take. We don't so much hate each other as we hate the prospect of our own irrelevance.
Me? I pretty much subscribe to the "bag of meat—ball of rock" theory. But it's a pretty fun ball of rock, and there's some pretty interesting bags of meat running around on it, so I figure I may as well enjoy my time here and try to get along.
