Same thing that has been unethical and immoral for centuries. Sexual perversion, lying, steeling, murder, false witness, oppression of the innocents, rape, adultery. It is not God's morality that is changing; it is people's acceptance and tolerance that has changed.
I have 8 simple laws I follow that fall into being as moral and as legal in my behaviors and mentality as possible. Moral codes work. Its good to be principled. Everything else I just let my conscience or heart decide. My heart is better than my mind. I have a good heart, but sometimes I can be cold, and sometimes think of things that I know aren't right. Meditation has helped me deal with my ailments tremendously.
