Well, I wasn't talking about being for or against war in general. I was just saying that opposing a war or supporting a war (especially in this case) doesn't have to have anything to do with being right or left. It does have a lot to do with one's view on the morality and constitutionality of a war... and yes, the necessity of one.
And to answer your last question, yes, I think all good people oppose war unless it is necessary, just and legal.
How would you label yourself politically?
Is Ron Paul your candidate?
