You may have thought that the Scottish government had abandoned gender metaphysics after the collapse of the ‘Gender Recognition Reform (Scotland) Bill’ last year. Think again. The SNP government appears to be heading back down the non-binary rabbit hole. This week it issued official guidance to public bodies suggesting that they should record public identities under no fewer than 24 gender categories. These include, in no particular order, genderqueer, genderfluid, bigender, androgynous, non-conforming, pangender, and neutral.
