Sorry about the rather extended delay here, but I don't have as much time to spend online as I might like...
Regardless, I enjoyed reading your replies, and I hope to be able to respond in kind.
relaxeus, I would agree with you that laws are typically the result of having the majority of a society agree on something, but I am curious as to what you would say about a society in which deliberate betrayal and murder of "friends" is considered a high virtue. Since betrayal and murder is the norm, does that make it right for those people?
CSmrw, I've done a bit of thinking about some of the results of a personal liberty-based moral system, and quite frankly, I would agree with a number of the conclusions that would be reached in such a system. However, I'm curious as to your take on whether adultery should be condemned (and why), as well as your take on no-fault divorce laws. Would adultery conflict with the non-cheating spouse's personal liberty? Likewise, if one spouse wants to divorce the other simply because he/she wants to marry somebody else, does that conflict with the personal liberty of the person who wants to remain married?
charmtrap, I would dispute the position that objective morals are inherently "arbitrary", and so I'm wondering what makes a moral code formed by a Deity arbitrary, and a moral code formed by the mind of man not arbitrary. Could you explain the difference?
In answer to your hypothetical, Since God hasn't said murder is right, I don't know what I would think. The world would be a very different place, and likewise the social norms. For an example, I would refer you to the not-so-hypothetical question I asked relaxeus. (The line "Don Richardson: Peace Child" makes a decent google search. I don't have time to track down any specific links though.

chipmunk, I think you raise some excellent points. Completely removing one's bias from
any subject is impossible, IMO, especially in regards to such a touchy subject as morality.
However, the choice of the word "should" was deliberate. By stating that morality is solely the opinion of the individual, doesn't that exclude the possibility of attempting to force others to follow it?
(Just for the record, Jesus' command in Matthew 7:12 gives me all the reason I need to at least listen to what you say about morality. Obviously, agreement isn't included in that, but at least I'll listen...)
