I agree. At local sessions that I attend, Bluegrass purists are called "Bluegrasssholes", and "Bluegrass Free Zones" are declared, where people can play Blues, Gospel, Old-Time Country, Swing, etc.

Ironically, when Bill Monroe and Earl Scruggs were new artists, they were considered iconoclasts, with no respect for tradition, because they were breaking new ground musically.

Too bad that their followers aren't as creative and open-mnded.
