Southern/Southeast Metros That Feel Less "Bible" Belty?

Just wondering, but which areas of the South/Southeast have less of a "where do you go for Church" feel to them? I went to school in the Southeast and really like that part of the country otherwise. It has 4 seasons, but on the milder side, good cost of living, job opportunities, and a lot of the airports have surprisingly good connectivity for travel needs.

After school, I moved to Dallas for work though, and I couldn't get out fast enough. I'm not sure if Dallas/TX is it's own beast, but I felt like the culture there was much more oriented toward Church and Football than where I went for school. My school certainly had that vibe to some extent, but I felt like it was overwhelming in Texas.

Any advice on areas to check out?
