I don't follow you. What impact does my atheism have on my legal status?
You can be in three states.
Moral - morality is not defind by the individual but based on Godly laws.
Esthics - based in a moral code.
Legal - rules as defind by institutions.
Athisim leaves only a legal state as it does not have by definition God as its base.
These are my opinion, nothing more nothing less.
