someone hasn't learned the difference between personal, anecdotal experience and empirical evidence.

i think what i said does count as empirical evidence. i worked there for several years and this pattern continued week in week out, i.e. over a sample of at least 500 meals with that pattern coming up far too often to be chance. it is at the very least empirical evidence of the difference in tastes in pizza between men and women over that menu in that part of south london.... and women prefer the gowletini, men prefer the american hot.
As has been mentioned, that's different roles in obtaining food, not different eating habits. I see no evidence which would support an idea of gender based genetic food preferences.
