"If we confuse dissent with disloyalty—if we deny the right of the individual to be wrong, unpopular, eccentric or unorthodox—if we deny the essence of racial equality then hundreds of millions in Asia and Africa who are shopping about for a new allegiance will conclude that we are concerned to defend a myth and our present privileged status. Every act that denies or limits the freedom of the individual in this country costs us the confidence of men and women who aspire to that freedom and independence of which we speak and for which our ancestors fought."—Edward R. Murrow

For those old enough to have lived through the McCarthy era, there is a whiff of something in the air that reeks of the heightened paranoia, finger-pointing, fear-mongering, totalitarian tactics that were hallmarks of the 1950s.

Back then, it was the government—spearheaded by Senator Joseph McCarthy and the House Un-American Activities Committee—working in tandem with private corporations and individuals to blacklist Americans suspected of being communist sympathizers.

By the time the witch hunts carried out by federal and state investigative agencies drew to a close, thousands of individuals (the vast majority of them innocent any crime whatsoever) had been accused of communist ties, investigated, subpoenaed and blacklisted. Regarded as bad risks, the accused were blacklisted, and struggled to secure employment. The witch hunt ruined careers, resulting in suicides, and tightened immigration to exclude alleged subversives.

Seventy years later, the vitriol, fear-mongering and knee-jerk intolerance associated with McCarthy's tactics are once again being deployed in a free-for-all attack by those on both the political Left and Right against anyone who, in daring to think for themselves, subscribes to ideas or beliefs that run counter to the government's or mainstream thought.
