@FreedomBeforeEquality: Irrelevant. Gender is a social construct. Gender is a mindset; Sex is physical. Gender is not determined by sex. It does not matter what I have in my pants, besides underwear, if you were wondering.
Of course it doesn't matter what you have in your pants. What matters is whether or not you have a Y chromosome. That is the biological basis for gender. Gender roles are the mindset. Gender is scientific reality.
