It's not as black and white as you may think.
I could care less about who's fault this or that is, it makes no difference to me. I have many many friends in the armed services mostly Marines and Natl Guard. I support every one of them but don't tell people to support something you have no first hand knowledge of, you only know what you are told and that's what you are supposed to know. They are free to blame the President, terrorists, or the tooth fairy if they like that's what this country is about, choice.
I remember Sept 12th very well ,it was the day the world as I knew it ended, and I think a lot of people felt the same way, not just because of the actions of desperate mislead fanatics, but because our freedom was under attack and we knew it. We also knew our country had changed and would continue to.
I saw friends of mine who did not support the war being labeled as hippies and terrorists and that really ticked me off, they were free to do what they wanted and if they were not afforded those basic rights, (to protest or to support) then there was nothing left to fight about IMO. Freedom works both ways, support the president support the war or don't I don't care but don't ever think this issue is a black and white as the media has lead you to believe it is. This "your for us or against us" bull crap is dangerous IMO. You have a right to be neither or both just don't judge people because they don't agree with what you think is the truth that's how fanatics are formed, and that's how lines get blurred.
