Sometimes the only resolution to violence is (threat of) superior violence. If you’re a child and a group of kids attacks you, that’s “adults resolving the situation”. Anything else is a failure of the schooling system.
These are all things kids need to have the freedom to learn to resolve without a parent just jumping in all the time.
Such conflict resolution can come handy in adulthood for things like dealing with angry/complaining customers, miscommunications causing arguments, professional disagreements etc. I've seen so many people who are completely unable to do conflict resolution of any sort, everyone's always walking on eggshells around them knowing that any conflict is going to end up blowing up into full "Karen"-esque argument.
Find and exploit their weakness publicly thereby robbing them of their power.
I do not think you understand conflict resolution and should probably study it a bit before speaking so authoritatively. The basic gist of it is to identify the root cause of contention and identify the best practical solution. Most people bad at managing conflict fail to correctly identify the cause and empathize with the opposing view. Keep in mind - you do not need to agree with a perspective to understand it and failure to understand the other party is a responsibility shared jointly regardless of righteousness.
