Oh geez. This is gonna be, what, the 3rd 9/11 argument?
Look, I don't care that certain tragedies cost more lives than 9/11, the fact of the matter is thagt people died and it sucked. I know people say "get over 9/11", but it's a huge event that impacted America. They won't forget it anytime soon. History-wise, 11 years is still really recent. You may bitch that people are still bitching about it, but just think /why/ they are. If you're tired of hearing about 9/11, you'll have to wait a few more3 decades. Sorry.
Aaand hate on me all you want, but I agree with DERP about people maybe being traumatized from losing a parent. Do they not have the right to mourn about it since it happened 11 years ago? Seriously people. I know 9/11 didn't affect you personally, but it did affect others, so have a little more respect.
