The media will never let it rest... It is a way for them to make people freak out & think that something is gonna happen on that day again. That being the case... The peoples will never stop making a deal over it.
Personally.... I don't let it affect me too much. Yes, I do feel for the families of those who died {both American and otherwise}.. & I also think it was a terrible tragedy, and a scar on our country..... BUT, It's not something I let frighten me into hiding in my house on 9/11 every year.
You have to let people deal with it in their own way.. Death and tragedy effects us all in different ways. So no, you are not an insensitive jerk, you just deal with death in your own way.
