I think there is an "objectively correct morality" - treat others as you would have them treat you. Or to put it another way "my life is mine and your life is yours - neither of us have the right to impose anything on each other".
Discussion
I believe all morality is ultimately subjective. I subscribe to a moral and ethical system, and I stand up for it pretty vigorously. But I don't believe metaphysical claims can be made about my ethics.
