The man of frank and strong prejudices, far from being a political and social menace and an obstacle in the path of progress, is often a benign character and helpful citizen. The chance is far greater, furthermore, that he will be more creative than the man who can never come to more than a few gingerly held conclusions, or who thinks that all ideas should be received with equal hospitality. There is such a thing as being so broad you are flat.
