There is no universal "southern" culture the way you're defining it. While Baltimore is certainly nothing like Atlanta, neither is either anything like Tallahassee.

I'm not just making this up. This is the generally agreed upon definition, that "In popular usage, the Mason–Dixon line symbolizes a cultural boundary between the North and the South (Dixie)" https://en.wikipedia.org/wiki/Mason%E2%80%93Dixon_line#Symbo...

If you just want a list of which are the southern states: https://en.wikipedia.org/wiki/Southern_United_States
