I don't understand what there is to be upset about. It's simply a set of numbers. It doesn't have any relevance to the event of September 11th. I was old enough to understand what had happened. I remember the uncensored footage from news channels literally showing people jumping to their deaths so they wouldn't die in flames. And I remember the phone called hours later notifying my family my aunt was missing. And almost 4 days later her body being found. Seeing 9-11 doesn't upset me, even though I have a bad memory of that day.
OP you're looking to be angered by something, and it's silly.
