Obviously I dispute this notion of "friendliness" in the South, as it only exists in certain cases among people that are considered worthy. Listen to your fellow southerners' comments about places like Massachusetts, Vermont....or (gasp) France.
I've never heard a Southerner say something negative about Vermont. France is despised by conservatives in all parts of the country, and the comments about Massachusetts really only pertain to gay marriage.
Nothing compared to what Northerners (even on this forum) think about Mississippi.
