There was this song from early 80s by UK band Discharge: "Free Speech for the Dumb".
It came to US when Metallica covered it in early 90s and people there though that it was praising free speech - that 'even dumb deserve free speech'.
Meanwhile the song is about empty phrase that 'free speech' is. Empty phrase.
