OK, one of folk music's claims to fame is that it champions causes, but that doesn't normally include being mean-spirited.

Any time you sing a song that's anti-something, there's likely to be someone listening who feels angry or embarrassed, but at least their personal discomfort's private. The point is, we can't usually identify a person's 'sins' by looking at them, we just hope the song is making someone think again.

But someone's appearance is there for all to see. Singing about it is bullying and I wouldn't want to be part of an audience that's asked to applaud it.
