I can only assume this is due to regional weighting, because if I compare it to all other respondents in the UK where I'm from, I'm to the right of the average and of course the structure of government over here is a tad different to that of the United States.
I'm a traditionalist anti-nanny-state Tory Boy and card-carrying Christian to boot, who supports the military provided it's engaged for OUR national defense not the defense of others. And I answered accordingly. It even recognizes that I'm socially conservative.
I can only assume that by indicating in my answers that I'm socially conservative that makes me a statist, and because I think "Peace-keeping" exercises don't constitute "defense of the realm", they actually think I'm a pinko anti-war infiltrator, and on those bases scored me well to the left of where I probably ought to be.
Still, if Jim Robinson thinks they're right, at least I can say I got in before the ZOT.
