I haven’t been following the responses to this monograph, but I’m not surprised that at least a significant number of the hostile reactions seem to have been textbook specimens of the ad hominem logical fallacy:
“As Predicted, Gay Activists Attack the Messengers, Ignore the Evidence”
Does it really need to be pointed out that personally attacking the authors of a book or article isn’t a substitute for examining the evidence and analysis on which it rests?
(And yes, I’m fully aware of the fact that I’m routinely accused of having made a career of doing precisely that — an accusation that is both slanderously untrue and, yes, a further example of an ad hominem fallacy of diversion and irrelevance.)
