You know it because it makes you feel better, perhaps? Or you have some kind of emprical evidence to show it?
Sure, you might disagree with the "support our troops, protest the war" argument -- but someone who believes that thinks about the war in a way that is NOT THE SAME as someone who believes "support our troops, and thank Gawd we're doin' it!" If you TREAT the positions as identical, you do NOTHING to advance your argument.
But don't let that interfere with your fury...

"The fact that so many Muricans (okay, >= 60% of Muricans) can adopt this position is perhaps the greatest condemnation of a Peeple that can be conceived."

Really? That's interesting. The GREATEST condemnation? There's no position they can hold that would be MORE condemning? Well then, we must immediately convince 60% of the "Murican Peeple" that we need to wholeheartedly support the random execution of Iraqi citizens -- on television -- by firing squad. I mean, at least then they won't be committing the moral atrocity of having inconsistent
and contradictory opinions on the war...
