Some people react to whaling songs the way others do to an overt expression of religion. (Check some of the posts on threads about whaling songs and you'll see)As far as "one way" - I was taught that Christ died for the sins of the whole world...which means to me believers and non-believers. I cannot believe in a god who would condemn a soul for lack of knowledge - and thus by extension a lack of belief - in Christ.
Add to that the many fine people I know who are far more "christian" in their outlook and behavior then many Christians I know (this is judging by the teachings of Christ - not the tenets of the churchs descended from his teachings)
