No, I don't think that it would be a good idea for Aspies to have our own World Government.
I think that we are citizens of the governments where we live.
So another question would be, should people who are on the spectrum move to some private island somewhere and form our own government there?
I would say that would be fine for the people who want to do it, but i would not want to move there, personally.
Among other personal reasons why I would not want to, I have some family members who could not live there who I would miss too much.
For example, what about "mixed marriages" and what would happen if a baby were born there who was not on the spectrum?
