What is moral relativism?

Moral relativism is a term that describes the idea that people's understanding of morals, ethical standards, what is right/wrong, etc. is shaped by their culture, life experiences, education, and so on. Basically, it means that there is no universal understanding of what morals are because morals are individual. Everyone shapes their own idea of what is moral or ethical. What might be ethical or moral to one person is not automatically ethical or moral for another. It is logically invalid (provably wrong) in the Normative case and generally considered false in the Cultural/Societal case. The Normative Relativistic Theory is invalid due to a contradiction in its premises. The Cultural/Societal theory is held to be false by nearly all (if not actually all) modern philosophers due to an invalid inference in its premises (namely, that the same ethical belief can not be upheld by different moral practices in different cultures)
