Strawman theory
The strawman theory (also called the strawman illusion) is a pseudolegal conspiracy theory originating in the redemption/A4V movement and prevalent in antigovernment and tax protester movements such as sovereign citizens and freemen on the land. The theory holds that an individual has two personas, one of flesh and blood and the other a separate legal personality (i.e., the "strawman") and that one's legal responsibilities belong to the strawman rather than the physical individual.
