I think for most Americans, knowledge of the Islamic world was pretty slight before 9/11, and then it was thrust upon us in one of America's darkest hours, and the perception was through the polarization of that terrible event.
我认为大多数美国人，对于伊斯兰世界的认知 在 9·11事件之前是相当欠缺的，之后却被 美国最黑暗的几个小时内 发生的极端恐怖事件 强化了对伊斯兰世界的偏见。
