Kim Kardashian -- Declares Civil War! North Way Better Than South

Kim Kardashian just went off on the South ... declaring North the greatest direction of them all -- though she's clearly biased.

KK wasn't breaking down the Battle of Gettysburg -- she was talking to Shaquille O'Neal on his podcast (yep, he's got one too) ... about the public pressure to name baby #2 South West.

TMZ broke the story ... Kim isn't going back to that well, and is opting for a more traditional name this time around -- but listen to her diss the whole notion of the South, or any other direction.

As she puts it ... they're all "lower" directions.
