Why is Carleas banning Cock and Balls?
Fuck You Carleas! Trump won, fucking live with it, you're not enacting your Progressive Final Solution on my private parts.
You may request Trial by Combat legally in the US, the argument that it is illegal because dueling is illegal is invalid, as sparring remains quite legal, in practice and condoned by the US military long after the concept if dueling was made illegal (see Audience Murphy "Red Badge of Courage for a civil war example, today Ranger Battalion still does it)
You merely gotta NOT KILL your opponent, and the laws regarding accidental death immunity in bouts apply if you cab show you merely sought to wound your opponent. Not all Trials by Combat resulted in death, as many were resolved by Crying Raven.
You have the legal right to fight your opponent, or he can seek a member of the local bar association in your state to represent him, under US Law in order to practice law, you have to be a member of a legally recognized law association, so they can't cheat by getting a cop to fight you, must be a lawyer. You can have the fight state or federal or county, as I've seen no evidence it was ever restricted. Not sure muninciple.
So, challenge him to fight till grievious injure or till one cries Raven, this is your right as a American. Everyone has a right to a jury trial via the courts, but not all courts are Jury, such as the DMV or Trials By Combat, or in cases of Arbitration and settlement, or plea bargaining. This is one of the virtues of living in a country that embraces legal pluralism and bijuralism. You get rid of trial by combat, many Supreme Court cases just after the civil war evaporate, as well as our claims post revolutionary war. It is a impeachable part of our legal system, as long as you have the balls to assert your ancient rights as a American.
