Well concerning subjective morality and objective judgement, I believe morality is measured by the law of God called karma. Do unto others as you would have them do unto you. Buddah teaches the same philosophy. The God within you judges you. You will be judged as you judge others, and whatever you do unto others you do unto God. I believe it is the same God in all of us, so I think the same basic morality is within all. I think God is within even the unsaved, they just have to seek within and find God, accept God, and follow the path of love. I have nothing against Buddha and will not judge him to hell. Judge yourself first. I personally think the message is more important than the messenger. I don't think it is enough to believe in Christ, I think the important thing is to follow his teachings and his example.
Again, that is subjective morality. Some people can beat up others because they like the fight (like I know many fellow Marines do). Therefore fighting is ok as long as you are willing to accept the physical consequences.
Jesus Christ said 'do unto others' as He was surrounded by Believers. In context, He meant treat them as you know God wants and how you were treated by God/His disciples before you found Christ. He does not mean accomodate different desires if they are not holy.
There is a basic human morality and, according to evolutionary psychology (by far the most scientific, objective psych lens), that morality is selfishness and hedonism.
If you don't mind, I will repeat an analogy I convey to Travis:
Buddhism, as I know it, has the user define what is right and wrong. That is easy. "I won't think sexual thoughts between 2-3pm AND I won't have sex with more than 2 women at a time!"
I remember when I was young and very self-centered--I thought everything I did was right because I was so superior to everyone else. By Buddhisms standards, the Borg of Star Trek are right in destroying whole cultures to elevate them and absolve them of their petty choics.
In summary, the whole premise of Buddhism is that there is a basic, dignified human morality. There is, but it is not dignified.
