Many people see relativism as necessary for promoting tolerance, non- judgmentalism, and inclusiveness, for they think if one believes one’s moral position is correct and others’ incorrect, one is close-minded and intolerant. I will argue in this chapter that not only do the arguments for relativism fail, but that relativism itself cannot live up to its own reputation, for it is promoted by its proponents as the only correct view on morality. This is why relativists typically do not tolerate nonrelativist views, judge those views as mistaken, and maintain that relativism is exclusively right.
