Haenfler (sociology, U. of Mississippi) takes the first close look at sXers, the straight-edge young whose commitments may include vegetarianism or veganism, environmental issues and social movements. He describes, sometimes from first hand, the core values and the emergence of straight-edge life as a subculture and social movement, the inter-movement struggles between positive sXers and militant elements, the effects of subculture life on the formation of masculinity and femininity, the ways older sXers refine commitment, the inroads of commercialization and the Internet, and the lingering after-affects of good intentions.
