 Each of the sorts of reasons just offered is controversial. Consider three examples of this controversy. First, it is controversial whether the sorts of puzzlement reactions identified by Hare must signal conceptual confusion or misuse (Kramer 2009, Harrison 2013). For example, perhaps we take ethical supervenience claims to be so obvious that when someone appears to deny them, we are inclined to treat conceptual confusion or difference as a charitable hypothesis. One potential piece of evidence for this is that when denial of ethical supervenience is based upon reasoned arguments, such as those mentioned in  Section 5  below, a diagnosis of conceptual confusion or difference arguably become less plausible diagnosis.
