"One man's vulgarity is another's lyric." Harlan, Cohen v. California (1971) It is probably no accident that freedom of speech is the first freedom mentioned in the First Amendment: "Congress shall make no law...abridging the freedom of speech, or of the press, or of the people peaceably to assemble, and to petition the Government for a redress of grievances."
