What about all those songs that extol Jesus? I don't like the way organized religion tries to push people around, but some of the religious songs are glorious. At what point do these songs become offensive? Is misleading people about science and restricting public health worse than killing and eating animals? I think it is a matter of degree.
What about songs in which women are abused or denigrated? I recall once when someone was singing "The farmer's cursed wife" ("The devil & the farmer's wife") there was a woman who was getting angrier and angrier verse by verse until "This proves that the women are better than men..." Then she smiled.
