You don't have to be of a specific nationality, religion, or race to realise just how terrible that day was. As an Arab I just want to say that I'm terribly sorry to anyone who has lost someone they loved because of it, I just want people to know that you shouldn't resort to hate, judge, and generalise people without getting to know them individually.
As a child at school I grew up with the idea that I have to be wary of Jews. One day I met this lovely Jewish woman from Argentina named Marianna on a plane heading to Madrid, and I realized just how dumb and naive that kind of thinking was. Now I know that they are people just like me, many of them happen to be lovely and are very warm-hearted. The day I met Marianna was the day that I started to have my own beliefs and my own opinions as an individual, to me she was a godsend, I might not have the same views that I have today if it wasn't for her.
Right now I'm really angry that my religion has to be judged because of 9/11, while the person responsible is currently hiding in a cave or a sewer (the latter is probably more true) somewhere without giving a f*** about the fact that some people have to wake up every morning and have to deal with the reality that the person that they love and lost is never coming back or the contempt and prejudice that people like me have to deal with wherever they go because of him.
Once again I just want to say that I'm really sorry and depressed about this.
