Biology says we're social creatures with a natural tendency to assign leaders in the group, and there's nothing wrong with that;
Rules of biology, as in the simplest of terms, rules, laws and maxims alike Define most everything from math to Here, on Hive, and all definitions are but limits and lines in a conceptual realm, no different than a rule, so why not, lets rule out that there's not one single thing wrong with the leader follower dichotomy which completely disregards any other options or roles?
In the end, morality is like any vacuous whim that can't or ought not be defined, what is ones Self Defense is another's Murder. What is theft, lying and otherwise cheating when morality is YOLO? Those things are just as subjective as the self defense v murder. Rules, those things that people came under consensus to hold one another to, a standard, which I'm sure you detest in numerous ways as if almost unable to recognize the glaringly obvious reality that the overwhelming majority comes to agreement and the implications of that. The golden rule from someone that said from the beginning when it was clear from the video that Kyle was shooting in self defense, instead you screeched murder. Morality in the moment, lol
