Yes, warpus, it was very necessary.
The thing you're missing is that it was not me, but
THE MOVIE that created an unkind connection. The Na'Vi doomed a planet of TWENTY BILLION PEOPLE (at a guess: in the sequel, the human race is not gonna be happy about that--they will come back to Pandora, and they will be
PISSED THE HELL OFF). The connection I made, between the U.S. and Haiti, is a much more pleasant one: we, the U.S./Na'Vi, are willingly sharing our unobtainium, at a pretty hefty cost to ourselves.
Now, here's a real-world analogy that parallels the movie
almost exactly: the U.S. and North Korea (I mentioned this before, but apparently you didn't get the memo). North Korea is very literally a dying world, much more so than Haiti. North Korea didn't get whacked by a single disaster, it has been dying and starving for half a century. North Korea been looking outside their borders for an economic boost. They are mostly looking to the U.S.--and they are
threatening nuclear war. And, just like in the movie, the U.S. is telling them they can go neural-queue each other.
The symbols in the movie don't only represent indigenous peoples who got stomped on. They ask a much wider question: when you have something that somebody else desperately needs, should you share or not?
It's not as simple a question as most Avatar fans wish it was. For example, any naturalist worth his salt can tell you that you should
not share food with wild animals, because the animals start to become dependent on humans and lose their ability to survive on their own.
Unrelated side note: while surfing further on "The Blues" (the frequent cases of depression experienced by people after seeing the movie), I had a revelation. I found a number of people who wished to live the way the Na'Vi do. Well, here's the problem: the only way we can have Pandora out here in the real world is to
accept the existence of predators who eat humans. Guess what, warpie, that's never gonna happen. No intelligent creature can abide the existence of predators; the only reason all other prey animals put up with predators is because they don't have opposable thumbs and have no power to change their lot. Humans will never accept any of the available methods to control our population. Living in harmony with nature?? Hmmph. Not gonna happen. Ever.
Edit:
here's a little something to read about what happens when we humans get friendly and cuddly with our fellow living creatures (in this article, deer). Their population explodes out of control and they become a problem.
