3. Subjective relativism and tolerance are two different things.
Some people may be attracted to relativism because they believe in tolerance. There is a lot to be said for tolerance. It allows individuals in a pluralistic society like the United States to live in harmony. However, tolerance is not the same thing as subjective relativism. Subjective relativism holds that individuals decide for themselves what is right and what is wrong. If you are a tolerant person, is it okay with you if some people decide they want to be intolerant? What if a person decides that he will only deal fairly with people of his own racial group? Note that any statement of the form, "People ought to be tolerant is an example of a universal moral norm, or rule. Relativism is based on the idea that there are no universal moral norms, so a blanket statement about the need for tolerance is incompatible with subjective relativism.
