a proportionate means of achieving a legitimate aim (12. 413)

With today being International Crab Day, around since Jurassic times and with one of the most complex and contentious cladograms in Nature, we show some extra respect to a museum in Margate dedicated to the marine crustacean for championing transgender rights after the UK Supreme Court, sadly taking a cue from the US culture wars, ruled that women are defined by “biological sex” to the exclusion of transgender accommodations, and whilst not eliminating rights and protections completely nor declaring that there are only two sexes as in America, it is consequential insofar as single-sex services including restrooms, changing rooms, hospitals, prisons, sports clubs and shelters. The judgment however specifically stated that the biological characteristics delineating men from women are assumed to be self-evident and requiring no further explanation or nuance, according to the court’s interpretation of the Equality Act of 2010—to which drawing on its expertise in evolutionary history and biology the museum countered that there are no binaries in Nature and it was an abuse of science to suggest sex and gender was not on a spectrum. Other institutions have spoken up in solidarity, expressing rigorous opposition to changes in intimate spaces.
