Oh! so it's about beating a teenager not a wife. I still agree with the idea of singing anything you feel comfortable with.
I do see another potential problem with this song though. It's not only about child beating, it's about the behaviour of a group of people - Hillbillies, presumably, or rural families in general. It could be seen as unfair as sung by city folks. I don't think I'd sing it. Having said that I do sing songs about other evil aspects of human behaviour like murder and rape - but not songs that support those acts. Bawdy songs without violence are another matter. We all enjoy sex and we all like rude words.
