Basically a bunch of people who claim to not be citizens of any nation and will therefore try to claim they essentially have diplomatic immunity no matter where they go. Combine that with the personality and knowledge base of a meth fueled jailhouse lawyer. Actually, that's an insult to meth fueled jailhouse lawyers and I take that back...
But then the country you are in needs to recognize the country you're a diplomat of and want those diplomats in their country. Diplomatic status is not a "I can go where I please" status. But it's that way to sovereign citizens, I guess.
