Elders and mentors have an irreplaceable function in the life of any community. Without them the young are lost -- their overflowing energies wasted in useless pursuits. The old must live in the young like a grounding force that tames the tendency toward bold but senseless actions and shows them the path of wisdom.
It would be far more constructive if people tried to understand their supposed enemies. Learning to forgive is much more useful than merely picking up a "stone" and throwing it at the object of one's anger, the more so when the provocation is extreme. For it is under the greatest adversity that there exists the greatest potential for doing good, both for oneself and others.
