As above with 'transage', once you're on the ladder of bizarre beliefs - and insisting angrily that something obviously untrue IS true and berating other people for not believing in it too - where does it end?
If you told them that your dog, or your pet snake, or your washing machine identified as a human girl and thus IS a human girl, and so wants to be a fully engaged member of GG, and treated just like everybody else, how could they possibly tell you that you're wrong and refuse to include them?
Surely their official membership records would have to read 'Emily, Olivia, Charlotte, Rover, Slippy, Hotpoint, Maisie...' - and all of their activities would have to be planned with them all in mind, including parades where they have to make arrangements for Hotpoint to be dragged assisted all along the route, as 'she' cannot walk by herself.
Unless they're nasty, unkind, uninclusive, discriminatory bigots, of course.........
