I favor moral relativism as a general “rule of thumb” ... but i am opposed to making it a universal absolute—except for possibly in some deep and abstract way, below the level of basic human values, below, maybe, even, the basic tendency of life to develop values which promote more life.
Relativism is a meta-ethical claim, is it not, rather than a prescriptive one?
EDIT: I see now there is such a thing as normative (prescriptive) moral relativism. Strange view. Does anyone really promote or hold it?
