I would expect you to get ranted at because of its alignment with the Confederacy in the Civil War, which otherwise pretty much defines "the South" as a geographic term in common usage. South = Confederate states, North = Union states, West = a few physically separate states and various non-state territories at the time. At least with the North and the South, less so with the West, these groupings lasted long after the end of the civil war due to the effects of reconstruction and cultural identity related to the outcome of the war.
