Double Negative Bigotry — 

We've probably all heard the grammatical rule against using double negatives, but did you know that it came from clergyman Robert Lowth who declared it a sin against the King's English? Chaucer and Shakespeare used many double negatives as a double emphasis. In Appalachia, an Elizabethan dialect is still widespread. It's common to hear people say things like "ain't never" or "don't need no" as a double emphasis. It is perfectly acceptable speech in its cultural context, with just as much right to its own grammatical rules as other varieties of English. Some linguists believe that rules coming from prejudice in favor of only the King's dialect need to be reformed. Some Christians love making rules, but we are justified by faith not law. The Old Testament contained over 600 laws "imposed until a time of reformation." (Hebrews 9:10 NASB)
