[Interesting]

i did not read the entire thread, but speaking to the thread's title, there's simply two genders.

Male
Female

all that falls in between are 'abnormalities' in sense that somewhere along the genetic coding and biochemical make up, an abnormality occurred that caused said gender to act out of line to the 'majority' or 'norm'.

with that being said, this is to be respected and recognized, violence or out right hate is not a viable way to react or deal with this reality.

Also, for all that fall in between, they might disagree with my statements, but i think this is due to their unique position in life and their strive to find a solid identity that can be 'official'.
