Anyone can demand what they like, it doesn't mean that they can have it. In the right place, at the right time (which are not "right" because of adherence to any standards, by the way), I will happily sit through one or more songs that I would consider poorly performed, simply for the joy of allowing someone to "have a go". In a song circle, a singaround, a singers' night, I will impose no "standards" on the performances. If I don't like it, I can walk out, or I can never visit that place again. That's my choice, and I do not need any standards to justify it, just my personal taste, which of course can differ wildly from someone else's.

The trouble with standards is the need to keep their definitions simple, if they are to be implemented (and "policed", which you must do, otherwise why have them in the first place?). But tastes, especially in art, are complex and do not lend themselves easily to definition. Which is why we have such trouble with labels. And standards of course lead to labels.

Standards do not need to be extreme to be mis-applied. All it takes is for someone to put a definition down in writing, and for someone else to interpret it their way, and you have the makings of a disagreement.

What's worse, standards do not need to be strict before they can stifle creativity. Ask Wella of this forum what were the standards that resulted in her only ever singing to herself in the kitchen for the first 60 years of her life - only for the rest of us to find subsequently that she has the most wonderful alto voice.

It's only my humble opinion, but I stick with it so far. Until someone persuades me otherwise.
