I hate the fact that people use 9/11 as a carte blanche excuse for this kind of crap. That's unacceptable, 9/11 or not. Seriously, get over it. It's a hole. People died. Memorialise it, throw flowers in it, whatever, fill the hole, build something and move on. We need to stop dwelling on the past if we're to move forward. 7 years isn't long enough for "closure"?
Seriously, what's the difference between "We will not be silent", "Nous ne serons pas silent" and نحن لن نصمت?
ABSOLUTELY NOTHING.
