Was that satire?
As much as 1.7% births are considered intersex. There are people physically both from birth. This woman has never heard of hermaphrodites? Whatever the percentage, it is consistent, has always been, and will always be. Likewise, the percentage who mentally identify different from chromosomes is consistent throughout the ages, in all places. For every man who identifies as a woman there is a woman who feels better as a man.
This says something about man's maker. Look around and see a binary world, polar opposites existing along a continuum, all shades of grey in between. Human gender issues are no different. Also, look around and see the predominant law in effect is constant change. Likewise, sexual preferences are constantly changing.
As such, it appears man's maker suffers bi-polar syndrome, and instability of mind. So what is wrong with equal rights among the mentally ill? From another philosophical point of view, any gender ID is included in the mental illness.
