Cultural Relativism And Moral Nihilism

The belief that nothing is morally right or wrong(moral nihilism), and the belief that morals are culture-specific(cultural relativism) seems to be in retreat everywhere. There are 2 motivations for this - 

1. Moral dogmatism(negative motivation)- those who wish to dogmatically assert their own values without worrying that they may not be as universal as one might suppose.
2. Positive motivation: Not believing in any universal values which should be propagated and defended. Allan Bloom worried that this trend would lead us to lose our "selves" or identity across society.
