Anyway, back on topic... maybe.
I don't think everyone should feel obliged to sign up. Some people benefit society a hell of a lot more not waist deep in mud and getting shouted at. I mean, can you really see Einstein at bayonet practice? *thinks* Actually I find that notion strangely terrifying.
"I haff proofed, as you can see on ziss blackboard zat zey don't like it up zem."
I just have difficulty grasping the notion that one genuinely might have such degraded social conscience that you'd cheerfully leave everyone you've known, and everything that made you who you are to get trampled by some invading swines. I really don't mean that to be insulting. I'd like to understand, if you could explain.
