This question drew a lot of fire, comments, arguments, and close votes, but I'm not sure that it should have been closed. The arguments for closing seem to center around the question not being about an interpersonal issue and not having a clear goal.
I would say that responding appropriately to a live performance that you find objectionable is in fact an interpersonal skill. There are clearly interactions between the asker and the performer and/or the asker and the other audience members that clearly involve interpersonal skills.
The answer that the question received before it was closed seems to demonstrate that pretty well.
I also think that the question had a pretty clear goal. The asker didn't like the content and was looking for an appropriate response.
Now, I understand that many people probably found the assumptions and implications of the question somewhat offensive and may have reacted largely because of that. But I don't think the question crossed the line into rude/abusive and as far as I know, disagreeing with a questioner's point of view isn't a reason to close...
So, am I way off base here or should we take another look at this with cooler heads?
