Depends on what you mean when you use the word central, Essorant.
Banning people is not a "dominant or controlling power or influence." On the contrary, it's extremely rare.
However, expecting everyone to take responsibility for their own words and actions, which must include bearing the known consequences of their actions, will always be "of basic importance" and "essential" to any social structure, including these forums.
What you fail to see, Essorant, in your idealistic naivety, is that enforcing responsibility does much more than simply protect the community. It is equally important to the individual. Platitudes of love and kindness are easy, and largely meaningless, if you're only willing to do what someone else wants of you. Feeding a ten-year-old cake and ice cream for dinner every night isn't a sign of love, and giving an alcoholic a drink will never be an act of kindness. Moving beyond platitudes will often, and perhaps always, require hard choices. Taking the easy path is the greatest cruelty of all.
I would honestly be much more impressed with your passion, Essorant, even though I feel it is misguided, if you weren't so quick to forsake it. You lament the abandonment of an individual, through banning them, even when the individual is in direct conflict with the needs of the community? You insist the community should never give up trying to resolve the conflict, even when there seems little hope the individual will ever listen?
Yet, what happens when no one agrees with you? What happens at the first twinge of frustration? Your answer, it appears, is to abandon the community. You seem to be very quick, Ess, to turn to exactly the same solution you accuse us of employing. Apparently, you are no wiser in reconciling irreconcilable differences than are we.
