Blessed are the pure in heart, Jim, for they shall see God.

Jesus didn't think being thought of as a purist was abuse.

I don't see why you are so shy about the term...purist.

Your concept of 'folk music' is a million miles variance from common English usage. Evrerything from Ralph McTell, to James Taylor, Neil Young - I heard all those called folk music at the funeral this week of someone who thought of herself, and whom the world thought of, as a folk music aficionado.

Its a term like 'sea-green incorruptible'. You know your colours - why not nail 'purity' proudly to the mast. Sing if you're glad to be gay, and all that...
