I have no idea what they mean by strawman.
My understanding of this sovcit insanity is that the “strawman” is a legal entity that the government uses as their placeholder. The strawman is a US citizen and all that comes with it, but the actual person is not. They believe that the rules do not apply to them because it is only the strawman that is bound by laws and rules, and not their actual self.
A lot of this loonacy revolves around the belief that they are legally separated from their strawman, and use all sorts of forms, “rules”, and excuses to “prove” this.

EDIT: No edits! It stays as it stands!
I reject your English and substitute my own. I will force the language to make sense over time.
