It's not about "working class", it's about individualistic elitism and ostracism. Introspection and opposition to all of the world's agents that are against you and your will. Inversion of power, inner exploration, self-knowledge, liberation, and ultimately ego death. Dark enlightenment on a Nietzschean level that transcends labels and broad application due to the particularities of each true listener.

Or, put simply: Judas Priest is fuKKKing killer.
