Thanks for chiming in. :)
When it comes to morality, I think we do have to risk taking a stand somewhere to say, "Hey, I think I know this. What do you all think?" To me, the NAP is a great base point. If we claim to know nothing, then morality itself can't exist because every action will be completely subjective, regardless of how harmful it is.
True, i guess for me its always a question of whats moral to one may not be moral for another. We are all a product of the bias that we come from and carry that throughout our lives. But yes i agree that having an open discussion about this subject will bring people onto the same wavelength hopefully.
