I think the solution is to spell out the standards.
Require newbies to learn the standards and rules,
prove they know them, and agree to live with them
before they are allowed to post here.
Then, if they violate the rules they can be reported and banned.
Anarchistic gang enforcement is not even advocated
by libertarians like me in private spaces. Set the rules and enforce the rules. You don't need a gang of thugs for that here.
I'm really surprised that you consider the stupid, childish insult "go take a hike" to be worthy of such heated reaction.
Or worth bothering Jim Robinson about.
You want everyone (else) in the world to be perfect or you're going to complain to the authorities?
I have found that polite, intelligent, and warmhearted people vastly outnumber the opposites on FR.
