To quote Edward R. Murrow. "We must not confuse dissent with disloyalty", which pretty much sums up the difference between people who believe in free speech and fascists. "We cannot defend freedom abroad when we are making it weaker at home". Going to other countries to defend freedom and American values as we are crushing those values at home for the American people. That is what this debate in the early and mid 1950s was about.
Ed Murrow and his nightly newscast See it Now and their investigation into Senator Joe McCarthy's committee hearings about supposed Communists inside of the U.S. Government put CBS News on the map as far as TV in this country. And probably led to the CBS Evening News with Walter Cronkite that eventually became a half-hour show. Because Murrow and See it Now took down a movement that was trying to destroy free speech and assembly for the rest of the country. Which is what Joe McCarthy and his supporters were about.
