I think Azizi knows full well how she stands on the use, etc. Of course, the word "assess" in this context can mean different things to different people ...

It would make sense, though, for Azizi within the pages of her prospective book to: 1) acknowledge the existence of other dialect writing/singing; 2) recognize that the intent of such dialect writing/singing can vary (broadly: positive, negative, neutral); 3) recognize that the effect may not correspond with the intent; and, 4) recognize that the effect of the use of dialect as well as the understanding of the intent of such use may change over time.

I offer that for her use FWIW, not to try to get an argument going. I would hate to see her get so bogged down in the subtleties and permutations of the use of dialect in Cornish folksong that she never gets her book completed ...
