many political pundits like to define the map as between right and left, but in all honesty most of us find ourselves somewhere's in between.
If you really take a look at the political landscape (and this would apply to most countries) the political discourse is really dictated by a small percentage on either side (left or right) who are the most vocal about their issues. Those of us in the middle tend to get washed out cause we're: a) not as vocal, nor b) are we taking an easily definable position (simplicity sells, complexity sinks).
There tends to be a huge identity crisis in the US today as to what defines the right and the left. The right has historically been about fiscal conservatism, yet we have a republican administration that hasn't followed this. They've taken social conservatism and almost done away with the fiscal side (practically shifting towards libertarian...privatize privatize privatize). As for the left, they've continued with a socially liberal agenda, but fiscally they've practically moved into the conservative arena. My point here being that what we've historically defined as right and left has shifted considerably.
As for the war, I would suspect that your homeland may have much to do with your leanings towards the conservative side on that issue, but I will also say that I disagree with this equating of liberalism and pacifism. When it suits the liberal agenda, they will shift from one side to the other. For example, Iraq is wrong cause we should only use the military when we're attacked, yet another repressive gov't, ie. Sudan, we better run in there as quick as possible. To ignore possible comparisons between the two or to refuse to take a deeper look at the issue than simply "saddam didn't have WOMD" is just putting up the usual liberal blinders when it doesn't suit their purpose.
feel like I've been rambling on senselessly, but bottom line, screw this modern day right-left defining, most of us are in the middle and if we ended this turf-battle between the two maybe we could actually get some better things done...
