@Triggerpod - you say male and female brains are different. As a working scientist (and one with a fair number of citations to my name) - can I have your peer reviewed sources for that, please? (Ideally open source, so that everyone can have a look at them).
Then get Gina Rippon or someone of similar stature on Triggernometry to discuss it. In fact ideally two - maybe one neuroscientist who agrees with you, one neuroscientist who disagrees.
From what I have read, for aspects of cognitive performance where there are measurable differences in the means of the male and female population, the d values (difference in means divided by product of standard deviations) is tiny, much smaller than for height, for example. And furthermore, this is a difference which can be explained by brain plasticity as easily as by innate characteristics.
Even with a difference on average in brain performance/structures on an MRI (hell, even that most obviously sexually dimorphic feature of all, brain weight, much beloved of the Victorians as an explanation of why women were suited to home and hearth), that wouldn't establish that there were "male brains" and "female brains".
Consider being asked to bet a tenner on someone of height 5'10" being male. Done repeatedly, you'd be quids in - that's what the statistics tell us. But you might not want to do it as a one-off and that tenner was your train fare home. And it would be clearly absurd to suggest that that difference in averages in overlapping populations meant there was such a thing as a "male height" or a "female height".
Insofar as any cognitive differences are measurable, you'd probably not want to bet more than about 10p on brain differences.
