Is Moral Nihilism a Morality?

[The Grand Nudger]

I'm giving you examples from your own comments about nihilism that present themselves as normatives. 

Can you explain how any of those comments are actually expressing anything normative?

Yes, but you don't need my help, you've explained it yourself in thread, here;

Not if you're correctly an Error Theorist or noncognitivst.

The normative statement here is that error theorists and noncognitivists should not or ought not, or can't x -presumably, because if they did, they would not be error theorists or noncognitivists correctly.

 Normatives don't have to be coherent to exist, and they don't have to arise from a coherent position to exist.

Did I say that normatives have to be coherent to exist or did I say that a position has to be coherent in order to coherently express something normative?

You asked me this question, here;

What's more, how can an incoherent position express normative function (or any function for that matter)?

Unless normatives must must be expressed by or derived from coherent positions then the coherence of the position has no relationship to whether or not normatives can be expressed by it or derived from it.

There are things a nihlist shouldn't do, and things a nihilist should

Does this imply that a nihilistic position expresses something normative or says that anybody ought to do or avoid doing anything?

That which we should and/or shouldn't do is the definition of a normative function.

Does talking about what Nietzhere believed about nihilism actually answer my questions?

It provides you with the background.  I'm not the first or only person to notice that nihilism can provide normative functions.  Nietzsche noticed it, and contemporary ethical theorists wonder whether any comment on morality, even a metaphysical position, can be completely divorced from normative functions such as should/should nots and desert properly understood and genuinely held.  What you call correctly.

Consider this.  If an error theorist is compelled by their position to deny the truth of the moral statement "x deserves y for z" - they have stated that x does not deserve y for z. A negative assessment, but, ultimately..still a comment on desert.  This is, possibly, why Nietzsche thought that nihilism contained impulse to destroy.
