Irving, Texas is not typical of what most consider the deep south. It's part of the DFW metroplex which is in the nation's fourth largest population center[1], and it's in a county that went 57% for Obama in the 2012 election[2]. So let's just be careful about painting wide swaths of the country with an singular view.
