These "Sovereign Citizen" groups are a menace.

8. Is that a statistical standard or statistical aberration?

"there are black sovereign citizen groups..."

Is that a statistical standard or statistical aberration? If the latter, the demographic most associated with the movement becomes the de-facto face of that movement. Which is why American neo-Nazo groups are collectively referred to as white, even though one organization had seven minority groups within it.

And, as no one has argued that the SC are 'exclusively' white, you appear to be arguing against a premise no one other than you has put forth.

Kudos on your consistency, though. Who know what it will reveal next...
