Atheism and Ethics

[Sheldon]

I don't see how the basis for anyone's morality can be anything but subjective, even theists. My own morality is based on the idea that we should strive to avoid and where possible prevent all unnecessary suffering. Now while I can make objective assertions about ways to best achieve that, it remains my subjective opinion that unnecessary suffering is bad, or causing it therefore is wrong or immoral.

I have never seen anyone who is able to offer an objectively moral or immoral act?

I understand why people find the notion that morality is subjective very disconcerting, but that's not a reason to disbelieve it of course. Not if you care that what you believe is true, more than you value any belief anyway. Theists of course in my experience are emotionally invested in their religious belief, and thus bend facts to their belief, rather the other way around.
