That would be highly symbolic for the left, since it would mean that finally the biblical definition of man and woman would be eliminated. The left is fixated on destroying any influence that the Bible and human nature still have on life in this country.
The Left is engaged in an outright war on reality--on nature, itself. Egalitarian/Collectivism--the underpinning of Communism and most forms of Socialism--is not, and never has been, altruistic, idealistic, or calculated to improve the long term lot of any recognizable group on the planet. The underlying motives have always been an attempt to outlaw reality & legislate or force acceptance of cloud-borne fantasies that appeal to neurotics that simply cannot handle the realities of human interaction, which make the uniformity of society impossible.
Of course, the compulsion exhibited makes any real progress in dealing with real problems virtually impossible.
