I'll let you all debate the definition and the foundation of nonconformity.
But, there does seem to be a common theme of de-valuing the norms of society - whether intentionally going against the grain, or simply going ones own way, which happens to be a different direction than the "mainstream."
So, here's my question: if a personal value is in conflict with a societal value, why is it assumed that the more advanced and respectable choice is to remain in line with the personal value?
Personal values seem a little empty and unchallenging to me. I think it would be pretty easy to live my life in accordance with my own beliefs.
