I actuallt asked this a couple years back, and, if I remember correctly, it's a essentially the "PC" name that a large group of head cases, generally those associatted with the deep space exploration mission, chose for themselves, and it sort of caught on. I look at it as being an identifier for those who subscribe to the movement that head cases are not in the wrong, were victims in this situation, snd that simce the damage is done they should be accepted in society. Like I said, tho, it seems to be mostly attached to those working with Evo (I think tue term may have started on the Mars Base?) so I dont know how relevant it will continie to he now that their ship has left.
