guys 9/11 happened 14 years ago let's constantly mourn it so terrorists win
really, if you keep mourning 9/11, and "never forget", it lets the bad guys win. that's what they want- death and destruction.
by moving on, they lose. it's like ignoring that one kid in class who annoys the stuff out of you- he will eventually stop getting attention and will no longer have a reason to pull his stuff.
