Hi George, welcome! :)
The trick with politics is to make it a part of your story, and not the entire reason you are writing the story in the first place.
Be Rowling, not Rand. (Please, god, don't be Rand!
In other words: Avoid speeches. Don't write polemics. Make your characters interesting, make us care about them FIRST and then when you put them in situations they have to get out of (which can be informed by whatever worldview you wish), we'll go along for the ride.
As for me, I was born in Europe and am a socialist at heart... but only because I have too cynical a view of people to believe that anarchism would actually work.
(You might call me a disillusioned hippy if it wasn't for the fact that I'm far too young.)
Incidentally, I find it really interesting that you associate "socialism" with "military," because those are either entirely unrelated or opposite so far as I'm concerned. But perhaps this is a discussion best not held on a public forum, or at least shunted from the "introduction" thread to the "kitchen sink" area of the boards.
Fantasy's also a great place for unusual politics to work out. The contest's open to anything speculative, so don't feel like you have to restrain yourself to just Sci-fi! (Although, again, I'd recommend writing a story, and not a political diatribe thinly disguised as one.)
Looking forward to getting to know you and seeing your writing.
