A contrasting sort of hybrid theory holds the descriptive content of moral predicates constant.  Such views are often modeled on slurs or epithets, as explicated in a certain way. It is plausible and perhaps even standard to think of slurs as semantically expressing a certain descriptive property (being a member of such and such a group, say) while also conventionally expressing a negative attitude towards those with the property. Copp (2001, 2009) and Boisvert (2008) suggest that moral terms could function in the same way.  Here again there are various ways to work out the details.  Advocates of the approach can note that it has advantages over the previous kind of hybrid theory in explaining communication insofar as the descriptive content remains fixed from speaker to speaker (Schroeder 2009). And they claim that the view does so without undermining the standard hybrid explanation of the motivational efficacy of moral judgements. Other theorists suggest that pejoratives like ‘idiot’ present a better model than slurs (Hay forthcoming).
