Culturally, there is no doubt where 'the South' is. Some of the apologists and seditionist jackasses would like to include Arizona because we (as a territory) supported the Confederacy. Not due to slavery, not even a little bit. The south provided a company of soldiers from Texas to help with 'Indian Control'. The Apaches and Comanches took full advantage of the military withdrawal at the start of the Civil War. Last battle fought in the War was here.
