Actually my point was not about caring one way or the other.
I think over reaction on the part of those who are not part of the tragedy is wrong. Of course one would do something if there is something to do that would help but, as most times there is nothing outsiders can do that will actually help the tragedy, I find it to be an overstepping sense of entitlement and even emotional indulgence to glom on to a tragedy that is not yours. I actually find it disrespectful to those that are part of the tragedy and it seems to me to be a giant self -indulgence on the part of the outsider to try and claim a piece of it.
(I am not talking about going to a different restaurant which to me seems a response that would make sense on several levels)
Again I ask what could others have done that would make an actual difference. If nothing - then going on about their lives is the only rational response as far as I can see.
