The aggregate of individual ignorance does not constitute collective wisdom.

I think we should have that on the Folk Police t-shirts as being typical of the pedantic pomposity that runs, somewhat ironically, contrary to the very spirit of folk music & folklore, but not alas, to the mindset that finds itself drawn to such things. Otherwise, I'm a linguistic & cultural pragmatist - we are what we are and we do what we do. Just as there is no ignorance, there is no correctness; all is variance, change and very worthy of attention, respect and celebration.
