Testosterone and Estrogen are two very different hormones, and they effect people in very different ways. These differences result in some genuine asymmetries as regards abilities, both physical, emotional and intellectual. These asymmetrical traits are "superior" or "inferior" only in the most relative of terms, and as such cannot be used for sweeping generalizations and definitive characterizations.
Socialization of gender roles in all contemporary cultures also plays a significant role, as does genetics regarding any number of abilities (primarily physical).
There are, of course, nearly as many exceptions as there are examples of these asymmetries, and the plural of "anecdote" is not "data". Gender alone should never be used to justify discrimination; opportunity should be open to all without any institutionalized gender preferences or biases. Results should be merit-based (though so seldom are).
This is why I dislike the word "equality" as applied to the genders. They are not "equal": they are complementary and both are necessary for humanity to continue (at least for the foreseeable future).
Last thing: the use of the word "feminism" in the OP brings an unnecessarily provocative and polemical tone to the entire thread, with explains Freyasworld's many sardonic replies (I hope).
