It IS sweet. It's great to see the world coming together as one to support each other when a tragedy of such great proportions occurs like this.
On the flip side, it's a true tragedy when people are so blinded by anger that the only thing they can do is scream racial epithets or attack fellow AMERICANS because they're of non-European descent. Just a week ago a student at my college was confronted in the cafeteria for this very reason. Sickening, isn't it? It really gets to me, though, because I'm Japanese. No explanation is necessary. You're educated, you can figure it out.
