War.. what is it good for?

Why am I angry? Why should I get upset? It's not some hidden, subconscious thing, its not jealousy, its not hatred, or fear. The reason why I get angry is because while I feel my opinion can be swayed on some things, people justifying this war with tired rhetoric and endless, (now Meaningless) words such as Extremist, Terrorist, or Radical (that, they are usually unable to define) become fodder for a whole mentality that this war is right. People get upset with me for disagreeing with the war, like I'm some Anti-soldier/ military person. Honestly, I'm not and what pisses me off is supposedly, I'm disallowed by this logic to have more than one perspective on the issue of war. Why am I not allowed to have a variety of feelings about this?
Some people get upset with me and say, oh you are going too far. But, don't be offended for someone else. You have to wake up everyday as yourself, and be accountable for who you are, and as long as I'm an American, I reserve the right to speak my mind. That to me is part of what makes our country great. But for someone to trash me, calling me out like I am ignorant (which I am most certainly not) when THEY are the true ignorant ones, is revolting to me. I shouldn't let my emotions get the best of me. But I believe in this world. I believe as inhabitants of this planet, we can all do better. This is not an us versus them thing that is going to be 1/ Productive 2/ Progressive 3/ Peaceful 4/ Rational. Without these Essential components, we cannot expect to live without war. The high price of this war (in both casualty on both sides, as well as national price, economic price) is not something that I take lightly. What also troubles me is that, with all the national problems we have, people still think its okay to try to argue that this war is somehow just. Lets take care of our own, make sure we are safe, and try to reconcile this horrible image of world bully we have somehow created by way of greed and ignorance. Thank you for 'listening'.
