That's not how I live my life.
If you think people don't reject binary divisions of sex in real life then you haven't gotten around much. You'd be totally surprised at the incidence of hermpahroditism. On m college campus there are many many students who live this reality EVERY day.
I'm not being polemical, just noting that I didn't claim rationalism would pretend to give new definitions to things or situations. If incidence of hermaphroditism is relevant (in general, or in a given situation), then it may well be entitled to be declared an absolute truth :) I still don't see the problem. Free at last! Free at last! Thank God Almighty, we are free at last! (Martin Luther King)
That's what I was responding to.
