Anything where people share any kind of common interest or ideals....is a clique.So what?...and who really gives a crap?
Humans have an annoying preponderance to categorize and define every little single little nuance of life...so that in some feeble way, they can further define their reasons for existence...and feel more secure about their surroundings.
Such is the nature of mankind.
Pain in the ass, and time better spent, practising an instrument.
