This one, for example.
For those that don't know, 'freemen-on-the-land' (or 'sovereign citizens' as they sometimes call themselves) believe that they can exempt themselves from legal liability with a cocktail of cod law, half-understood concepts, nonsensical documents, and plenty of arm-waving. No 'freeman' argument has ever stood up in any court in the world.
My worry is that this site will get bogged down in debunking these theories: I've tried to debate believers myself, but it's a never-ending rabbit hole of crazy. In my opinion we should not allow questions that are essentially polemic for a fruitcake theory.
What do others think?
