On a given subject, is one particular moral view objectively right and the others are wrong, regardless of what people believe? Or are people's beliefs and views central in the creation of morality itself, and thus morality is subjectively dependant on those beliefs and views. — PhilosophyRunner

My own belief is that there is an objectivity to what is immoral. This doesn't mean that it's always easy to discern, but for the most part we can see the harm done if we lie, steal, or murder.

It seems to me that rape is wrong because there is harm done, and, moreover, we agree that there is harm done. If there was no harm, then there would be no wrong committed.
