I think you bring up a very valid point. I've noticed this as well.
I'm not really sure why it's socially acceptable. Perhaps it is because when there are abusive relationships, it tends to be the husband that is the abuser and the wife that is the victim, so when the reverse occurs (or even talking about the reverse occurs) it's considered funny? Or, perhaps it is considered funny because several years ago, when women were treated as the husband's property, there was no way anything like this could be said, so it's a bit of "payback" now?
I'm not really sure what the reason is. I don't agree with double standards of any kind though. To me this qualifies as a double standard.
