A few years ago, thanks to Phoenix Jones, I discovered that there are "Mutual Combat" laws still on the books in parts of the US. I am of the opinion that this would be a great thing in society, assuming a few conditions are met.
1, that it must be a mutual agreement.
2, that any third party interference is considered aggravated assault at a minimum, and worse if they actually cause anyone harm (including state agents).
3, that this agreement can be made between any two consenting people, regardless of profession (including state agency).
4, the two involved can't harm anyone else, or anyone's property.
5, someone can rescind consent at any time, in which case any further combat is obviously not mutual, and therefore assault.
6, any injury resulting from mutual combat is the sole responsibility of the injured person, and not the other.
Obviously, must be conscious to give consent. Consent is considered rescinded if at any time one is unable to signal whether or not they wish to continue. Maybe two people would be required to find a third to agree to witness, and be a pseudo arbitrator/ref? I'm sure we could come up with some other considerations. My main point being, that it's not aggression, or a crime, but a mutually agreed upon contest, where each participant is responsible for taking part.
The reason I believe this would be a great thing in society is because it instantly eliminates a lot of nonsense kids don't understand about fighting. There are people who love to make a lot of noise, puff themselves up, and portray themselves as willing to fight, but who are not willing to fight. People who would dishonor others, with no concept of responsibility for their actions. As Rogan has said, there are a lot of people who want to beat someone's ass, but not a lot of people who actually want to fight.
Imagine a situation where things are getting heated between two people, or two groups of people, and one of them challenges another to a duel. Everyone there is now put on notice.... there is no need to yell & scream & put on a show about how much you want to fight, you either accept, or you decline. If you decline, you're just making a lot of noise, and no one else will take you seriously either. You can no longer hide behind society's desire for you not to fight, pretending that you would if you were allowed. Everyone else who was involved now must realize that any interference will be considered a crime worse than assault. In other words, any fighting without consent is an attack, and completely indefensible. A jury of your peers would have little to consider.
Literally there would be no harm done that wasn't deserved. Ever. Unless of course someone interferes, or attacks without consent, in which case they should be made an example of harshly.
We simply should not tolerate aggression out of any individual.
Extend this idea to the police. If police realize that at any time, anyone can challenge them to a duel (which is not a threat, but an offer), and if there is an acceptance, there will be no consequences for any harm done to them... the cops that have a problem being professional, with escalating vs deescalating, would learn really quickly that they can't hide their terrible behavior behind their badge.
Basically, it eliminates the noise out of the society because the buck stops with each & every person. If you don't want to be challenged, don't be a jackass. If you do challenge, or accept a challenge, you are on your own, and you've made your own bed, until you decide otherwise (or are no longer capable of it).
I think that dueling, or mutual combat, would be a fantastic thing for society. It's a bit like "An armed society is a polite society" in that we'd be forced to remember that there are consequences for being a shithead. People would mature pretty quickly. Aggressors would be seen as the cowards, and blights on society, that they are, and dealt with extremely harshly. Oh, and I almost forgot, this should give a pressure valve to society that isn't aggression/criminal, and would result in MUCH LESS KILLING! It would be just a great learning experience for everyone!
If any of you read through this disorganized rambling, I'd love to hear what you think.
