Just came back and read the thread having posted earlier.
I'm utterly in despair of the number of people condoning Smith's action and minimising by saying it was "only a slap" or he deserved it.
Dangerous and short sighted view point. And shockingly similar to the justification for male violence towards women, children and others of lower status that existed for 100s of years.
In this case people feel that Rock's hurtful words justified a physical response. Unbelievsble. Understanding the motivation for an action doesn't excuse it. And condemning the behaviour doesn't mean accepting the 'joke' was OK.
This thread has really depressed me.
