"In times of fear or hysteria· political, racial, religious, social, and economic groups, often from the best of motives, cry for the scalps of individuals or groups because they do not like their views. Particularly do we need to be dispassionate and courageous in those cases which deal with so called "subversive activities." They are dangerous to civil liberty because the prosecutor has no definite standards to determine what constitutes a "subversive activity," such as we have for murder or larceny. Activities which seem benevolent and helpful to wage earners, persons on relief, or those who are disadvantaged in the struggle for existence may be regarded as "subversive" by those whose property interests might be burdened or affected thereby. Those who are in office are apt to regard as "subversive" the activities of any of those who would bring about a change of administration. Some of our soundest constitutional doctrines were once punished as subversive. We must not forget that it was not so long ago that both the term "Republican" and the term "Democrat" were epithets with sinister meaning to denote persons of radical tendencies that were "subversive" of the order of things then dominant."
