Obsessed as in "doing science on socially relevant topics?"
> These differences are socially important because these tend to be prestigious occupations, and practically important because the different numbers of men and women in these fields contribute, in part, to the sex difference in earnings.1
So... "doing science on relevant topics."
Why misrepresent that as an "obsession?"
But I also think it's a fair question why gender differences are such a huge focus right now, as compared to say class problems (MOST Americans don't have $500 in savings [1]), or environmental problems (Men's sperm counts have gone down by half in the last 30 years [2]).
Obviously these aren't mutually exclusive, but there is a case to be made that the amount of energy/money going into this problem isn't proportional to its severity.
