If a performer of folk songs puts of a piece of singing and is only prepared to accept anodyne this makes him/her not only a revivalist singer but also a rather self-obsessed prima dona.
If you don't want discussion of your work - sing in the bath.
Discussion of people's work is not telling them what to do, it's part of the to-and-fro of the learning process - which is apparently why you have learned nothing.
As critical as you are of the revival, you are a revivalist - live with it.
As you said - nuff said
