Too often we honor swagger and bluster and wielders of force; too often we excuse those who are willing to build their own lives on the shattered dreams of others. Some Americans who preach non-violence abroad fail to practice it here at home. Some who accuse others of inciting riots have by their own conduct invited them. Some look for scapegoats, others look for conspiracies, but this much is clear: violence breeds violence, repression brings retaliation, and only a cleansing of our whole society can remove this sickness from our soul.
