Definitely one of the most surprising things I have ever seen a philosopher say is this comment from Parfit:

"If there were no [irreducibly normative] facts, and we didn't need to make [irreducibly normative] claims, Sidgwick, Ross, I, and others would have wasted much of our lives. We have asked what matters, which acts are right or wrong, and what we have reasons to want, and to do. If Naturalism were true, there would be no point in trying to answer such questions. Our consolation would be only that it wouldn't matter that we have wasted much of our lives, since we would have learnt that nothing matters" (OWM II, 367).

To start, I will agree that there is no need for condescending and insulting ways of responding to another person's claims.

Still, I hold that there are conditions in which it is perfectly reasonable to suggest that what a person asserts to be true about their use of moral terms is not consistent with the way they actually use those terms.

The difference comes from the distinction between knowing how to use moral terms and knowing that we use them in a particular way. It is quite common for a person who knows how to do something to not know that they do it a particular way.

My favorite example involves riding a bike. Many people who know how to ride a bike cannot tell you how they keep their balance. The way a person keeps their balance is by turning the front wheel and using their inertia to carry their weight back and forth over the center of gravity. We can demonstrate this. Watch somebody as they coast to stop. You will see them jerk the front wheel more drastically as the bike slows down.

We learn how to use moral terms as toddlers - at the same time we learn the rest of our language. We learn how to use terms like fault, duty, and negligence without learning any theory that we are using the terms in a particular way. When people explain what they are doing when they use moral terms, it is much like the person explaining how they keep their balance when they ride a bike.

Say that a moral realist and a moral anti-realist crash into each other at an intersection. You will have a great deal of difficulty identifying which is which. They both know how to use moral terms such as fault, should, negligence, and responsible, and they will both use these terms in substantially the same way. Their meta-theories are irrelevant. Each of them has a theory about what they are doing when they are using moral terms in this way, but it is quite possible for one or both of those theories to be mistaken.

Here's an example: Free will is not a part of the standard use of moral terms.

People who know how to use moral terms make no claims about free will. "Could have done otherwise" does not mean "has the ability to violate the laws of physics". It means "the causes of the behavior that produced the harms and benefits are of a type that praise and condemnation can influence". The standard use of moral terms does not apply them to hurricanes. This is not because hurricanes do not have free will. It is because shouting at a hurricane doesn't do any good.

Praise and condemnation emerged from the animal dispositions of anger and gratitude. Animals did not acquire these dispositions to express anger and gratitude because they somehow first evolved a false belief in free will. Animals acquired dispositions to express anger and gratitude because these were effective at nurturing dispositions to engage in useful behaviors and nurturing inhibitions to harmful behaviors. Humans are capable of asking more sophisticated questions about whether expressions of anger or gratitude due any good and came up with terms to refer to those things that people generally have reasons to respond to with anger (blameworthy) or gratitude (praiseworthy). There is no free will involved.

This explains Peter Strawson's observation regarding the existence of two types of reactive attitudes. There are objective reactive attitudes when the cause of a harm or benefit comes from something that anger and gratitude cannot influence. There are participant reactive attitudes when the cause of harm or benefit comes from something that anger and gratitude can influence.

Even people who claim to know that moral claims assume the existence of free will can still use moral terms correctly, just as people who claim that they keep their balance by shifting their weight on a bike can still ride a bike.

So, if somebody who knows how to use moral terms claims to know that they use them in a particular way, it is quite reasonable to ask whether their theory accurately explains and predicts how they use those terms. "Knowing how to use moral terms, would you say that this is a correct use of the term wrong? Now, does your theory say that this is a correct use of the term wrong?" If the theory does not match observations, then there is something wrong with the theory.

It could be that the correct theory concerning the use of moral terms shows that they contain an error - for example, a claim that the agent has free will or that objects of evaluation have an intrinsic value or normative property. One can propose removing the error and adopting a new error-free vocabulary. However, even this option must begin with a theory about how moral terms are actually used, and that theory might be mistaken.
