JB,
I also extend a welcome to you, as Mikey did, and assure you that wearing a 'Backs jersey would not get you mobbed and beaten. We really have a very good relationship with the Atlanta team, and its fans.
More to the point, I would suggest you look away from the City of Charleston if you are considering moving here. Job oppotunities and homes exist outside the city, and even the county. All still within easy travel distance to all the city offers. In your searching, I would suggest you explore what Dorchester County and Berkley County have to offer. Your wife would likely be welcomed by the local Red Cross Center in North Charleston, but you need not be constrained by residense for her to be employed by them.
I don't know from your post what kind of job you are looking for. But I suggest that if you are seriously considering a move, you look well outside the penininsula.
You will be welcomed, whatever. We can convert you. If you're already a fan of Battery West, changing to Battery East is a smooth transition.
