Good piece from The Barefoot Bum on Political dimensions. Take, for example, Iraq:

The trouble is that if you criticize the war along one axis, you risk by your silence on the other axes to be held in agreement. If you criticize the war as irrational, it sounds like you would approve of its aims if only they were being pursued competently. If you criticize the U.S. conduct of the war on moral grounds, you sound like you therefore approve of the morality of the opponents. If you criticize Islam, you sound like you’re in favor of the war. (I myself was accused of being pro-torture because I virulently criticize Islam.) If you try to criticize the war on all three axes, 90% of your audience will simply mutter TLDNR ((Too Long, Did Not Read)) and move on to something simpler.
