The fallacy sketched above occurs so frequently in the apologetics literature that I hereby label it the Apologetics Fallacy. The Apologetics Fallacy is the dialectical fallacy of assuming, in contexts of the sort sketched above, that because one has shown that D isn’t a rebutting defeater for P, one has thereby shown that D isn’t an undercutting defeater for P. A paradigm case of the Apologetics Fallacy can be found on pp. 291-292 of this article. And a paradigm case of the appropriate response to the Apologetics Fallacy can be found on the same pages of the same article.
