Absolutley disengenuous, and frankly beneath you, kelley. You *know* my argument doesn't hinge on coupling. The existence of two sexes hinges on the fact that the contribution of both--sperm and egg--is necessary for reproduction. Not whether they couple, or, as I mentioned, whether the fetus is nurtured within the woman before birth.
I invite you again to consider my real argument. Really.
