I think my biggest problem with postmodernism is that, in trying to be all-encompassing, it refuses to define itself. As an artistic form, there are few places that art can go from here.
And because of that, it refuses to examine itself either. Post-modernism is applied to everything except post-modernism. Thus, post-modernism has become the governing principle of literally everything, even fundamentalist religion, even anti-post-modernism! But no one stops to examine whether a post-modern life is one we truly want, whether its impacts are always positive.
Unfortunately, they aren't. Post-modernism, unchecked by any opposing ethos, has allowed morality to become basically nonexistent. It has removed the last remaining fetters on individualism, to the point at which community concerns and standards are meaningless, and if one ever tries to suggest that an individual has responsibilities to the community, one is labeled a socialist, a communist, a collectivist, a fundamentalist, a conservative, or an anti-individualist, depending on who's doing the accusing.
Post-modernism has thus created a world in which no one trusts anything, morality is no longer even subjective so much as it is dismissed and marginalized, and individualism trumps all else to the point at which there are no community concerns and all that matters is #1. Post-modernism and capitalism combine to create a terrifying, amoral, aggressive, brutal, individualistic machine of a culture.
