马丁路德金说过这句话吗？是那篇演讲稿的？

History will have to record that the greatest tragedy of this period of social transition was not the strident clamor of the bad people, but the appalling silence of the good people.

我找了半天，“I HAVE A DREAM”里没有，出自上面，《新闻言论》2010.4.14期微博广场上有，他本人从未说过，如果你要翻译，只有汉译英，我不想骗你！
如果你是认真的，请相信，网上好像找不到原文，废话，中国人创造的！
