I think the discussion needs to move away from the terms masculinity and femininity. They are too close in pronouniation to the words male and female, and that causes us to associate them as a derivitive: If you are male, you must be masculine; if you are female, you must be feminine. This is not so.
A better alternative are the age old terms of yin and yang. We are all both yin and yang. One cannot exist without the other. I can't seem to hyperlink on this computer, so check out this site: http://en.wikipedia.org/wiki/Yin_and_yang.
Me need to move away from either/or and move towards inclusion. I am you and you are me. We are one. What hurts you, hurts me. If you kick someone, then I have kicked someone, and that's not okay with me. We are all one in relation to each other.
Yin and Yang.
