"An alternative, workable and widely accepted alternative definition from anybody would be more than welcome. "

I don't think you really mean that. Alternative, workable, and widely accepted alternative definitions have already been presented and you have repeatedly turned your nose up for the definition that you have accepted and become comfortable with. You are disregarding any data that does not support your own theories.

We can run this thread to 1000 or more entries, and I fear nothing is going to change. I think the readers will judge for themselves and follow whatever definition they believe.

You aren't wrong in your beliefs Jim, there are just additional philosophies about folk music that you will never accept.
