You probably don't need another hot take on this, but I have some things for you to consider.
Will Smith came out of his chair and slapped Chris Rock after Rock made a joke about his wife's (Jada Pinkett-Smith) hair. Smith then went on to win the Best Actor award. This one is really complex, so let's look at it piece by piece.
Let's start with things from Will Smith's perspective, point by point.
Jada has a medical condition
Mrs. Smith has alopecia, which probably causes her great emotional duress. Will has no doubt had to comfort Jada many times about here losing her hair while trying to maintain a career in a very image-oriented industry.
This may have been the last straw
Will and Jada's marriage has been the topic of many, many jokes with plenty of innuendo about infidelity and Will tolerating it. Most of this has been very emasculating but up until this point, Will took it like a champ. Now let's look at the other side of the story.
Violence should never be the answer
This could have been handled backstage or the couple could have just left. Smith could have also have addressed his wife's condition during his speech, but then again he didn't know if he'd be making a speech.
Comedians make jokes
It was obvious that Chris Rock was just riffing. It's highly doubtful he planned the joke out or made any harm. Anyone can see that Jada Pinkett-Smith is a dang knockout and this hacky joke shouldn't have upset anyone.
So where does this leave us?
Pretty much everywhere. Your local internet expert that thinks they have all of this wrapped up (or that it was fake) is full of baloney. One thing you do have to keep in mind is that the LAPD got involved, so from a legal basis it did happen and was wrong as hell.
Let's wrap up with this
Rock once made a joke about O.J. murdering his wife, saying, "Now I'm not saying he should have killed her, but I understand." (Full context with profanities here). So I'm not ever saying violence is ever the answer, but in this case, I understand.
Providing Rock has no real pain and suffering, Smith should apologize and everyone should move on. It may be a minute, but in hindsight, Rock will look like the bigger man, while Smith's temper will be called into question every time someone wants to include him in a project.
