It is rooted in white supremacy because it comes directly from the Posse Comitatus movement. There are blacks who claim Sovereign Citizenship, but they may not realize that they cannot be Sovereigns because their citizenship was granted to them by the government. That's the deal according to the "purists" of the SovCit movement. Whites are SovCit by birth, but blacks can't be because an illegitimate government said they are and that's not legit.
The first one I ran into way back when was a part time self appointed minister, full time bigot, and purveyor of suppressor "kits" back in the pre-86 wild west years.
Next time I saw that guy, he was a featured case on America's Most Wanted.
