Alvin Plantinga writes:
The full meaning of the term, therefore, (in this use), can be given by something like 'stupid sumbitch whose theological opinions are considerably to the right of mine'.
It is therefore hard to take seriously... as a charge. The alleged charge means only that these views are rather more conservative than those of the objector, together with the expression of a certain distaste for the views or those who hold them. But how is that an objection to anything, and why should it warrant the contempt and contumely that goes with the term?
