in this topic i wouldn't like to talk of male/female, but of male and female gender roles. (a gender role being the PSYCHOLOGICAL buildup of an individual. There are males playing the female gender role, and vice versa.)

simplifying this a lot, those playing the female gender role tend to make decisions based on their emotions, which in itself limits their capability in tasks requiring logical (but slower) thinking. Those playing the male gender role tend to use their logical brain more, which gives them capabilities to mathematics, physics, and other logic dominated areas.

Although the female gender role looses in logic capabilities, it enables the player of the role to feel emotions such as sympathy and make rapid decisions.

It should be noted that, based on this and the existence of persons of certain sex playing the gender role of the opposite sex, we shouldn't be judged under the law by our sex, but the gender role we play. Also, each gender role is very much dependent on the other, and both shall therefore be preserved. The women's rights campaigns combine the gender roles to one idea, whereas, rather than doing this, both should be respected separately.
