In the context you describe I agree completely. But, not in the context that it was posted on. I would much rather someone punch me in the gonads than for someone to talk ill about my mother and sister - especially not my wife.
No two ways about it man.
the way your sister and mom is your izzet, same way your wife is.
If she gets mad and say some thing I don't think she should be looked at as a witch,
Also remember mashallah our stinky culture have turned marriage into a not so pleasure able thing.
Where you put in two perfectly fine individual and get a stinky out come.
That happens when you are not aware of evil forces working against you.
