As far as music critics go, for the most part I ignore their comments. I am well able to judge whether I like a performance or not.I admit that constructive criticism, rendered in a non-offensive manner, does have merits, though.
    That said, I have attended quite a number of folk festivals and it has been my experience that folk audiences are courteous and appreciative.Their harshest criticism is manifested by polite applause.I don't feel that they are "mean" to singers.
