I think the hardest parts to organise would be:
1. The land. Where would this metal civilization be? Someone earlier mentioned squatting. Squatting is not for a large group of people wishing to leave society. Although it shouldn't be so, every piece of land on earth (as far as I know) is owned by some government. Living on this land means everyone would have to subject to their laws, their punishments, their TAX (fuck!), etc: all the bad things that come with idiotic modern ruling.
What would we do? Buy a giant piece of land and ask them to remove it from their country? As if any government is just going to hand over land for a new country consisting solely of war-mongering society-hating metalheads.
I know! It's quite the bummer. Here's a couple of ideas I've been entertaining lately:
1. Antarctica and Pykrete. Antarctica is a whole continent free for the picking. Sure, there's some research and meteorology types down there, but they're few and far between and easily avoided.
We could get up a huge expedition to Antarctica and make immense floating cities out of Pykrete (frozen sawdust and water -- check it out on Youtube or History Channel). Since there's land under the ice in Antarctica, we find some places where it's not so hard to get to the bedrock, dig in and take advantage of the geothermal gradient for heating purposes.
So, we'd have a permanent base underground (ala Robert Heinlein's moon tunnel dwellers in "The Moon Is A Harsh Mistress", which also happens to be a terrific formula for pulling off a cell-based revolution) AND we'd have a bunch of floating Pykrete city-states trolling the seas.
People that can handle/see the validity of all forms of metal can man the Antarctic base. People who adhere to only certain types of metal can select whichever floating city-state suits them best, as each will have its own genre-based focus. In this way, we can avoid conflict between screech-loving Black Metal-heads and the deep gutturals of the Brutal Death crowd.
As fun as it could briefly be, waging war upon a country for a piece of their land probably wouldnt do much good.
Yeah, war is always more fun in lyrics and movies.
2. Things we'd need from modern society.
We cant make our own electric plants, computers, hospital equipment, internet, etc. Can we? How would we get stuff like this in this society?
I think you ask a very important question here. The answer is "Yes, the fuck indeed, we CAN!!!"
The trick, I believe, is selective recruitment. Instead of looking for a bunch of metalheads and hoping one is a doctor or engineer or computer scientist, find doctors, engineers and comp-sci people and see which ones are metalheads.
It's also important to note that every one of us has a brain. We can use them. I already know enough Physics, Math and Chemistry to contribute to the electricity generation problem or to learn how to make needed drugs like anti-biotics.
More importantly, I know how to read books. Everything we need to know (including modern medicine) is in them. 9/10ths of the subjects they program us to be intimidated by aren't really all that fucking difficult to understand.
Recall the scene in "Good Will Hunting" where Matt Damon rips Harvard boy an intellectual "new one" and reveals at the end that he got all his information by using his brain and his library card, and it only cost him $1.50 in late return fees.
Sure, there would be plenty of people willing to do this (fuck, i'm in), but what are the chances of there being enough numbers of:
-women (important: I can't be the only one who thinks most people on this forum are male)
- ...fuck it, im too tired. All the kinds of positions this society/country would need.
If the numbers arent high enough in these sorts of fields, do we seek others and try convince them to come live in our world? I'm sure thered be more than a few rejections there.
I addressed this part pretty much already, we would need to poll as much of the metal community (such as it is) as possible and find our specialists amongst them.
As far as music is concerned, I think it takes a special and highly developed musical intelligence to appreciate metal. If the musical intelligence is high, then there's a good chance other facets of intelligence will be high also. I don't think we'd have a problem finding suitable people for a functional metal society or learning necessary skills when we have to. We metalheads are fucking smart. We don't need any trained robots.
If anyone rejects us, then, of course, fuck 'em. Their loss. If they want to listen to lame music and be a slave to the NWO, that's not our problem.
