The kind of courage that we usually think of first is battlefield courage, a strength of character that can take a man (or a woman) into harm's way for a worthwhile cause, where he (or she) is likely to get injured, captured, or killed. An altogether different kind of courage has less to do with scars or medals than an ability to stand strong against one's friends when they are not only wrong but dead wrong. It's the difference between physical courage and what even the Nazi butcher Adolf Eichmann called "civil courage". In 243 years of American history, vastly more damage has been done to the Constitution and the Bill of Rights—to American values and the American way of life—by a lack of the latter kind of courage than of the former.
