It is commonly considered rude to keep silent in the company of others, but voluntary silence connects rather than distances us from others whose individual differences temporarily fade away creating a shared feeling of harmony and oneness.
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.
