It would be nice to have some kind of a link for that. Incidentally, I honestly don't see the harm in referring to male/female/men/women/boy/girl. I recognise the sensitivity around these issues but you should acknowledge that most people would far more quickly know what you were talking about if you used the conventional terms, flawed in your view though they may be. "People with 2 X chromosomes" doesn't cut it. And, let's face it, that isn't the only obscurantist reference in your post.
