I take your point, Al. I have in the past self-edited a song as it made reference to losing both legs which I - as the singer - thought was inappropriate. That doesn't mean I should demand that the origial version be 'cleaned up' and replaced with my edited one.
Whenever you sing a song, the likelihood of offending someone is always there. You could sing the Irish Rover and have one of the audience burst into tears because their dog had recently drowned. So, where do we stop? That's the big question. I think obviously a bit of decorum should be used when picking a set for a known venue and audience however, it's impossible to cover all the bases of sensitivity unless you want to restrict yourself to singing "Doh A Deer" and songs of that ilk.
