I'm divorced, and it wasn't because my wife wasn't subservient enough.
My point wasn't that you only see divorce for that reason, it's that people who complain that divorce rates are "a bad thing" at all, that's the root of their position; that women should not have the capacity to leave abusive men.
I'm totally supportive of divorce, precisely because I know how many good reasons there are for it (having lived through the ordeal, myself).
