The unintended consequences once sex becomes merely a state of mind is the end of women’s sports. If sex is purely a personal declaration, synonymous with gender, then there’s no reason at all to make a distinction in sports teams. Legal discrimination, in the sense of separation, requires verifiably distinctive categories. The ascendancy of the individual will inevitably result in removing any protections for funding “both” since there is no longer any such thing, and as funding cuts inevitably occur, fewer teams will be supported. Since crowds like winners, only those teams that win will be supported, resulting in biological men generally being who plays.
