The idea of singing songs about rape or sexual abuse in the public domain is disgusting. Just stand back and consider that sentence. You wouldn't stand for it in any other walk and if you gleefully sing stuff like that whilst necking the ale and having a laugh all the while, you're indulging yourself, not highlighting a moral injustice.
To argue other wise is the height of ignorance. With any luck the guy is getting at least a beating a day, the poor lass must want to hear none of it let alone a load of ale heads singing it in their scores with an ear to ear grin. They need to get over their selves ffs.
Whether we have our own skeletons is a complete irrelevance to that.
