Well, I guess it can't be handled on a legislative basis (GA Leg.) as they are the ones that passed that law in the first place.
What's wrong with it, is that the decision in fact violates the right of the church to allow ccw, if they want. That is a right that is their property right and should not have been violated.
In fact, the decision seems to talk about their wishes on their private property, while the decision runs directly contrary to their wishes (as to the church that wants to opt FOR ccw.)
