Russell - “ claimant’s beliefs in biological sex do not achieve cogency”
Well I'd give my mortgage to hear how gender achieves cogency !
Given it can simultaneously mean an innate essence that is indescribable and changes depending upon who has it, a set of rules and behaviours, something that you can have one day but not the next, something they're not everyone has and some people have it and then they don't have it, some people have more than one, and some people have one after the other.
But none of them can be objectively identified.
