Most of the GGS-hatred I've seen has come from people who hate that Diamond rejects racial differences or innate differences in will and spirit ("civilization", "culture" etc.) as an explanation. Then there's some very few left-wing critics who hate it for basically the same reason, but with opposite sign, since it implicitly also rejects that western civilization or the white race is uniquely evil. Then there's some grumbling from academics who hate a popularizer for all the reasons you'd expect.
