I don't really believe the argument is whether the song is any good. I think there can be good, even great songs, which deeply offend a lot of people.

I'd also contend it isn't difficult in the least to determine in advance (most of the time) which songs will offend which groups of people.

So, if you make a conscious choice to sing songs knowing that they will hurt and offend, to me that is a whole different kettle of fish than singing a political song which is intended to be a critique of those in power.

It seems to me that there are certain types of arrogant, reactionary "folk singers" who delight in offending others, and stirring things up. But that has little to do with their politics, and everything to do with their personality, IMO.

And I agree with AliK--problems can also arise when it's a "my politics are better than yours" thing too.
