Re "A Quiet Triumph of Hate" by Al Martinez (Times, May 8): This is the most meaningful, serious and important article that Martinez has ever written . . . a prize winner. I hope the racist hate-mongers get the message. The most disgraceful and frightening thing is that the Police Department, the FBI and the postal inspector refused to become involved. It brings to mind the Holocaust, when the (people of the) whole world closed their eyes, while 6 million men, women and children lost their lives, and proves again that SILENCE is the most unforgivable sin in the world when there is a principle involved.
