I guess I've lived here most of my life and it's normal to me. You can literally strike up a conversation without almost anyone random and you won't get a disdained look back.
I think, in Texas at least, don't know about other areas of the south, many people will be surprised from how open people are in the cities. Now, in rural areas... yeah, no promise there. Rural people will love you at first site, but if you mention anything anything that contradicts their bible or the right to have a gun, most likely not. The cities surprise people who visit here though. They were not expecting the acceptance of things they thought everyone in the south was against.
