Metal stands against societies organized by dualistic (heaven versus earth) and liberal (individualistic, egalitarian) societies, as it denies that our values systems are more real than events in natural reality. Truth is a way we describe some things in reality, but there is no eternal life nor eternal truth which exists separate from immortality. Metal means accepting mortality, and experience as what we have in place of a religious or moral truth.
These ideas exceed limits of social acceptability, which in a capitalist liberal democracy threatens the self-marketing which individuals use to gain business partners, social groups .
To Nietzsche, and thinkers such as Arthur Schopenhauer before him, to realize this was an "undergoing," or embracing of nihilism: the belief that there is no value other than the inherent, physical interaction of the natural world.
To a nihilist, there is no inherent morality or value, thus there is no reason to view social status and financial success as ultimate goals, only as methods to a path ranked by subjectively-derived importance. This view threatens the beliefs and punishments used to hold Western society together.
