Sure, but what I really should have been saying was that their arguments are inconsistent. I didn't mean to directly appeal to the people.

Okay. Can you give a hypothetical example of such an inconsistency?

To a degree, I don't know that I can clarify because I consider the notion of imperative morality ("here's what you should do" as opposed to "here's what coherent with what you have and will do") to be inherently incoherent much like Nietzsche addresses the notion of God.

I tend to think of good moral arguments as advice, which is somewhere in between the two positions you describe. Simply describing the way someone has behaved in the past is not quite right, I think morality should make predictions about what actions will make someone happy/content/fulfilled/whatever. This has some relationship to descriptive ideas, but also goes beyond them and involves consideration of counterfactuals, choices, etc. I'm reminded of the concept of "revealed preferences" in economics, and the weaknesses and limitations that concept has.

See, I wouldn' claim that my caring is in any way relevant or justifying. As opposed to your relativism, I have at best an absurdism. Where I stop someone, I'm either invoking an absurdist morality, not a relativist one, in my claim that they shouldn't be doing what they are doing, or I'm invoking a descriptivist notion of the dynamics that led to my decision.

I used the word "justifying" in a way that might be misleading. My caring is a justification insofar as I declare it to be so. I'm not saying that there's an external objective way to assess whether or not a quality like caring is relevant to morality, I'm saying that it feels to me like my thoughts and values have normative power and so I respond to them as though they do.

I don't like the tone of absurdism. It is most often expressed in a sad or comedic way. But the arguments it makes don't intrinsically involve any such emotional reactions. I think it's negatively self-undermining to have a view with such pessimistic undertones, even though I agree with many of the same facts that an absurdist would acknowledge. I prefer other connotations to underlie my worldview, such as Nietzsche's descriptions of morality as a creative act.
