You're right, but as someone in the queer community (gay) the gradual evolution of human behaviours between the sexes (and genders) including gender roles etc (being broken down for some, but not for others) will possibly eventually result in a collapse of all meaning within this system.

There's many points to someone's biological sex, medical and other. But when it comes to gender, once stereotypical gender roles have completely broken down (if ever, we have evolution/genetic to thank for that) what difference remains in that distinguishing your own gender even matters anymore? None.
