I actually disagree; what neo-Kantians like Korsgaard do is argue, like Isaac, that normative commitments can be derived simply from something very minimal - in Korsgaard's case the act of deliberating - quite independently from any considerations of the advantages or disadvantages of various metaethical theories (non-naturalism, expressivist quasi-realism, or constructivism).
They then turn around and say that this essentially makes true a version of constructivism (or "practical realism"),
Well, Isaac won't even commit to that. He claims it has no implications.
I would possibly agree that people like Korsgaard are making extraordinary claims too. Extraordinary in this context is pretty specific. Rationalwiki has a fairly good article on the phrase:
https://rationalwiki.org/wiki/Extraordinary_claims_require_extraordinary_evidence
Extraordinary claims are not necessarily extraordinary in the sense that thy are
rare or
uncommon claims.
The evidence put forth by proponents of such things as gods, ghosts, the paranormal, and UFOs is highly questionable at best and offers little in the way of proof. Even if we accepted what evidence there is as valid (and it is highly debatable if we should), limited and weak evidence is not enough to overcome the extraordinary nature of these claims.
Nearly half of the population of the US believes in ghosts, and a significant part of them think they've seen ghosts. Despite the commonality, it's still regarded as an extraordinary claim in the way the claim to have seen a chair on somebody's roof isn't; the latter is composed of things we already know to be possible, even if not an ordinary event.

for reactions to it that I think are much like your reaction to Isaac, see e.g. Hussain & Shah's "Misunderstanding Metaethics: Korsgaard's Rejection of Realism." Although Korsgaard is obviously much more sophisticated and informed about the issues, I think that what Korsgaard is doing is a bit similar to Isaac thinking that we can use reasoning to establish ethical claims, and then turning around and calling mind-independent realisms about ethics 'retarded'.
Well, Isaac won't even engage on what mind-independence means. I agree that there are some similarities.
I have not read much on Korsgaard beyond a few terrible arguments I've seen presented from her; I did not get the impression that she has contributed anything substantive that can't be addressed through referent to Kant directly.
Maybe we can get into this at more length when the article on deontology comes up.
Margaret Hayek wrote: ↑Wed Nov 29, 2017 7:44 pmIn any event I think that you and I largely agree on the main issues: good practical ethical arguments like the argument from less able humans really are neutral as to the main metaethical alternatives (non-naturalism, constructivism, expressivist quasi-realism),
I don't think they have to be neutral, but if they claim to be and the user of the argument wants to avoid those discussions then they certainly need to be.
I don't think arguments from naturalistic realism are a problem since it's not that hard to argue for that position, and I would say that the strongest arguments are based on that; like arguments from sentience being the trait of moral value, and moral consideration being based on interests.
Margaret Hayek wrote: ↑Wed Nov 29, 2017 7:44 pmand the problem with Isaac (and Korsgaard, and AtheneWins) - unlike those who simply offer good meta-ethically neutral practical ethical arguments like this - is that he (and she, and he) essentially tries to show that substantive ethical claims follow simply from very minimal things like valuing oneself or deliberating.
If you're willing to commit to deliberation leading to naturalistic moral realism, that pretty clearly leads to consequentialism and some kind of preference based framework which necessitates valuing the preferences of sentient beings (as the only ones that have them in any meaningful sense).
I don't think it's a problem in itself, so much as claiming to be meta-ethically neutral while being nothing of the sort.
Korsgaard is just wrong. I'm not sure what AtheneWins does.
Margaret Hayek wrote: ↑Wed Nov 29, 2017 7:44 pmalthough what makes it less extraordinary (but more confusing) is that Isaac seems to use 'inconsistent' as synonymous with 'double standard'. I'm planning at some point soon to try to clarify this in the NTT wiki.
Just replacing that word would be a great way to improve the honesty and validity of the argument.
