Well evidentially that difference is still there is people feel the need to cross from one to the other. If people want to go to what is still a fairly extreme length to transpose themselves into a new viewpoint on life we should support them, but the gender gap is, I think thankfully, far from dead yet.
I reckon something fairly scary is might happen when they get round to making artificial sperm though, thus rendering men utterly redundant to even that most basic of biological process. Now how's that for scary?
