Are you tough enough to face one of the uglier stains upon the fabric of our democracy, prejudice? It’s the basic root of most evil. It’s a part of the sickness of man. And it’s a part of man’s admission, his constant sick admission, that to exist he must find a scapegoat. To explain away his own deficiencies, he must try to find someone who he believes more deficient. If you find yourself thinking words like “Nigger”, or “Kike”, or “Pollock”, or “Wop”, or “Bohunk”, or “Sheenie”, or “Dago”, consign them to the lexicon of race-haters who aren’t fit to breathe the same air as you are. Make your judgment of your fellow-man on what he says and what he believes and the way he acts. Be tough enough, please, to live with prejudice and give battle to it. It warps, it poisons, it distorts and it is self-destructive. It has fallout worse than a bomb … and worst of all it cheapens and demeans anyone who permits himself the luxury of hating.
