Our Founding Fathers were the first to articulate the reasons for their First Amendment, the same reasons given by Learned Hand, and by Justice Brennan in New York Times v. Sullivan . It is a lesson we keep forgetting and must relearn in each succeeding generation.
New York Times v. Sullivan was about the suppression of speech in the South [during the 1960s]. Today's version of suppression is just another verse of the same song.
I am sure that as soon as speech was invented, efforts to suppress and control it began, and that process of suppression continues unabated.
