Also, Kikosemmek those are some pretty good points there, the only moral absolutes we have are those we willingly impose on ourselves I guess. But don't you think that people should still be able to pass judgement on others because an action so heinously breaks an accepted standard?
Deciding what people should or should not do is an indulgence I keep myself from taking part of- I can say this: we all judge inevitably, because we are all imperfect and therefore succeptible to our own sets of morals or standards. A human is a gregarious animal, however, so do not forget that while many of us might agree on a set of standards or some other protocol, for whatever reason, the number of people sharing an opinion is no grounds for the opinion to be wise. Humans do, as experiments demonstrated, ammend their beliefs and reckonings to suit the societies they see themselves a part of, virtually universally. I cite the German 3rd Reich as a good example of this:
German wardens repeatedly abused and brutalized their captives in the concentration camps, and then broke down in tears when the Allies unlocked the gates. What's up? What happened was a swift paradigm shift in the perception of German society as a whole- under Hitler, the standard is to hate the Jew and those lesser to the Aryan race. Under Allied occupation, humane treatment of all people was demanded, and the people of the 3rd Reich had to cope with these shifts. One can marvel at how easily humans forget the pain of an insult in the vengeance they exact on their aggressors, as the moral gates of hell were basically loosened on the German footsoldier while no one ever considered how much choice he really had in the matter.
What's the lesser of two evils: agree to hate and torture another or have the same applied to you due to moral reluctance? For most people, as a realist, I have to admit that it's the former. In the end, people do follow their orders in fear of retribution.
In the end, people do serve their own needs, yes.

To give a less dissatisfying answer to your question, I'd say that I believe in a society where the only rules are those that apply to direct assurement of safety from social (murder; riots; chaos), political (war, foreign relations and trade), and economical (mass inflation/deflation of currency value; gross disparities between social monetary ranks) catastrophes, and in this and only this type of society can people be judged for breaking a law. The system we have now is far from what I describe. With this, I'd make it clear that to be part of a society one must sacrifice a bit of liberty and agree to such aforementioned rules. I'd also make it clear that any action that does not break the rules does not pass through the brain of the legal system.
How would this apply to our world? Gay marriage would be legal because there would be no law making it illegal, as homosexual wedlock is no direct or indirect cause of social, political, or economical crises. Abortion would be legal because the killing of a fetus does not directly cause social, political or economical crises. Note that I will contrast this with the killing of a grown human, which will carry with it a social problem, because those who are tied to the people involved will be affected and/or harmed. The recently departed would have probably been productive citizens, and their loss would probably evoke a a need for vengeance in friends and lovers. A fetus, however, carries with it less emotional baggage. If an abortion takes place, then it is because the mother didn't want to have it, for one reason or another (for the sake of objectivity, I'd also account for the woman being forced into the abortion: if the woman is successfully forced into it, then the powers that made her abort will definitely take no liking to the child once it's alive if the woman disobeyed the pressure). The death of a fetus does not incur the loss of a productive member of society.
Things like the murder of a human being would be illegal not because killing is evil or wrong, but because it will be a disturbance to the whole- a sudden loss of a part of the community- a lessening of the society's peacefulness.
If you care to know, I only harbor one moral code: honesty toward myself. Lying to myself is to me the greatest and only sin I can commit, and to better negotiate and understand my life and myself, I should not seek to hide or distort the truth, and so I will not play a bigot of any kind in sincerity. I guess you could call me a scientist, because that's really what science is all about: hard, objective evidence to find out a common truth we can all relate to. Anyone who tells you different does not quite grasp the essence of science, which is really a sharing of truth under the test and scrutiny of others. Only in this way may one be sure that all illusions are gone.
