Some might say that the only way to deal with this kind of tragedy is to laugh about it. For instance I know some very tasteless jokes about Diana's death. It's a kind of 'Don't let the b******s get you down' mentality.
On the other hand, I do feel that it's a bit tasteless. For the same reason that I wouldn't go around in a tshirt saying "**** you". You never know who you're offending, and do you really want strangers to only know you for that?
