I dunno, grey, I've always thought it's important to hold onto Sept. 11 precisely because it serves as a reminder of how idiotic all human conflict is -- along with Hiroshima & Nagasaki, the Holocaust, etc., etc. I've never seen any propaganda value in it whatsoever (though our illustrious President no doubt does, as you've pointed out). If anything, it reminds me of just how wrong the whole US strategy in the War on Terror is.
Oh, and maggie, I'm not sure about 9/11 jokes, but Marle x Magus comics are always okay.
