To be precise: This magazine is not promoting or condoning men hitting their husbands. The implication is, "hey, he's worldly, don't expect him to be peaceable."
It doesn't outright condemn him for hitting his wife, but I believe that's a given based on their other articles about how a christian husband should be loving..
The major fail is not what this paragraph is telling husbands, the major fail is what the watchtower is telling wives. Namely: If you are in a physically abusive relationship, you should stick with him instead of leaving. And that's just horrible advice.
