Morality is nature-made, not God-made. All you need is empathy, and it turns out that mammals have empathy, and so do birds and others. The golden rule follows from empathy.

Natural Law is NOT a new idea, really. Nor is it foreign to religion! St. Thomas of Aquinas is the father of Natural Law -- almost a millenium ago now -- and a big deal in Christianity. Natural Law is a big deal in the Catholic Church, for example. One might say that St. Augustine vs. St. Aquinas is just a religious expression of the Plato vs. Aristotle.

You'll find plenty of well-read, well-educated, very religious people who take a Natural Law approach to morality and who would agree that what happens in private between consenting adults is almost entirely moral (with some limits, such as perhaps that giving one's life up consensually is not moral). (I myself am agnostic, but still, I take a Natural Law approach to morality.)

Of course, there are schools of thought that reject Natural Law, but you must at least acknowledge Natural Law as a concept. And you should at least accept that Natural Law works for others even if not for you. You have to co-exist with the rest of us.

(Us noticing that other animals have empathy is fairly new though, I think.)
