I think you're dead wrong here.
First, most people, if not everyone, has experienced tragedy, loss, grief, embarrassment and so on at some level. The very reason people react so strongly to revelations such as those surrounding Tiger is that they have, indeed, suffered themselves (either as the victim or the perpetrator of sorrow) and they rise up to defend against this occurring to others. This, identifying and caring for the *innocents,* is a very human response.
Secondly, to condemn publicly a public figure's actions can never be "unkind." I think, rather, it's "unkind" to the innocents and society as a whole to remain silent when this type of outrage occurs.
Good points.
