Creation was brought up out of the chaotic waters by the making of distinctions and giving of names. Life and peace was possible on the basis of those distinctions and names. Reversing genders is an advanced stage in the rejection of those distinctions and names. It’s to take the waters as your god, and you become like your god, hence fluid, formless, ugly, chaotic, dead. You call out for the Flood to overtake you. God obliges, exiling you to Chaos.
