I'm not arguing against rules. I am arguing that a group of people is nothing more than the sum of the individuals in the group, and any morals and ethics that apply to individual continue to apply to those individuals whatever their organizational relationship. They may make whatever rules they wish, but each of them, as humans, still must comply with all the moral and ethical laws that apply to each individual. If attacking another human is wrong, membership in some group does not make it right.
I contend that society should have rules, and that those rules should prohibit any person initiating violence against another. Seems like that would advance the cause of civilization. I'm surprised and disappointed at the degree of resistance to this idea.
