I think, or at least hope, that many of us understand, and care, that "folk" music encompasses many traditions, and many histories.
And also I believe that those who have the ability have a responsibilty to keep the old way of doing things - the roots - alive, and yet also to build on them and so make them relevant, living, today. It shouldn't be too hard. People haven't changed much over the millenia.
How old are the ruins of civilisations. Look at them, and every time you see an old building, or just foundations, with "a bit added on" think
how many times did the conversation "let's build an extension on the house" - "ooh yes! what colour curtains can we have, and can we have a party when it's done" has occurred!
