The complaint against Chaplinsky stated that he shouted: "You are a God-damned racketeer" and "a damned Fascist". Chaplinsky admitted that he said the words charged in the complaint, with the exception of the name of the deity.
For this, he was charged and convicted under a New Hampshire statute preventing intentionally offensive speech being directed at others in a public place. Under New Hampshire's Offensive Conduct law (chap. 378, para. 2 of the NH. Public Laws) it is illegal for anyone to address "any offensive, derisive or annoying word to anyone who is lawfully in any street or public place ... or to call him by an offensive or derisive name."
Chaplinsky appealed the fine he was assessed, claiming that the law was "vague" and that it infringed upon his First Amendment and Fourteenth Amendment rights to free speech.
The [Supreme] Court, in a unanimous decision, upheld the arrest. Writing the decision for the Court, Justice Frank Murphy:
"There are certain well-defined and narrowly limited classes of speech, the prevention and punishment of which have never been thought to raise any constitutional problem. These include the lewd and obscene, the profane, the libelous, and the insulting or "fighting" words those which by their very utterance inflict injury or tend to incite an immediate breach of the peace. It has been well observed that such utterances are no essential part of any exposition of ideas, and are of such slight social value as a step to truth that any benefit that may be derived from them is clearly outweighed by the social interest in order and morality."
I love it, he thinks his old employers still want to use him for promotional purposes
