They have stepped out of the straight jacket of masculinity. They have transcended the limits of their culturally-defined gender. She too has transcended the stifling gender role society has for her. As long as we have gender defined the way we do, the limitations on women will remain. They will be suspect for acting powerful, assertive, decisive, and feminist.
Transgendered people embody our real issue.
And that's a major threat to everything that oppresses us. Society's fear is that if we take away the two gender roles we will not know who we are. In reality, we'll get in touch with our unconditioned humanity by rejecting externally imposed, dysfunctional, and inhuman, definitions of what it its to be human, male and female. We will not be free until transgendered people of all types can define who they are and how they want to express their self-chosen identities. It's not really about sexual orientation.
