I'm with Jim here. I find it tiresome and juvenile when the following happens:
1. A question is asked about the most (or least) suitable choice of songs/style of singing for a particular type of venue, region or event. It's usually (as in the above case) someone who wants to pick the best material to please their audience.
2. Various respondents give their views and ideas, which are intended to answer the question and give some helpful suggestions.
3. At this point, a few others jump in and start shouting "Fascists! Folk Police! How dare you tell me what I can and can't sing? I sing just whatever I like, in any way I want, and I don't care what anyone else thinks of it..." etc etc.

If you can't answer the question that's been asked, or you don't think it should have been asked in the first place, then you clearly have nothing to contribute. If the idea that some songs and performances are more appropriate, more skillfully delivered, more enjoyable to the audience, is one that makes you uncomfortable, why not just move on to another thread and leave the discussion to those who are interested in it?.
