“As Predicted, Gay Activists Attack the Messengers, Ignore the Evidence”

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.)
