===================
Key for lowercase letters:
gm = genetic mutation (outcome decided at birth)
i = identifying as (dress and other early stages)
pt = pre-transtion (on hormone medication)
t = transitioned (hormones plus surgery)
dt = detransitioned (read about it in Australia)
Can we think of any more? Imagine a high school track meet for this genital circus. I do think it should be outlawed worldwide to detransition more than once. You can go and come back but you can't go that route again (sick).
