Is it true that there is no absolute morality?

[SteveII]

Even in the broadest sense of the word, atheism (defined as an absence in a belief in God) is a position that contains no God. A worldview that contains no God affects key metaphysical questions like what is there? and what is it like?

Which can then both be and has been answered in any conceivable way, by atheists, so long as that answer contains no gods.  

Thank you for the thoughtful reply. I appreciate the dialog. 

"No god" carries with it far more weight that you are allowing. Can you avoid Naturalism being true in a "no god" worldview? If not, that comes with a bunch of metaphysical baggage having to do with epistemology, etiologic considerations, limited ontology, etc. 

To deny this seems like your way of evading the conclusion: atheism leads to things like life having no intrinsic (essential) value/purpose/meaning. How could it--we are simply the product of time and chance--two things that cannot endow meaning.

Being an atheist doesn't mean "a person who believes we are the product of time and chance".  I'd have to ask about the latter, ofc..if we were the product of time and cahnce...and we can endow meaning....wouldn't it then follow that time and chance can, in fact, endow meaning?  Your categorical denial of the ability to endow meaning by x seems more a convenience than a well thought out objection.  

I am not saying that atheist can't find meaning in life--but that is different than a theist's position that human life has value simply because it is human life (intrinsic/essential). 

An atheist is also capable of holding that position.  You may notice you made no reference to any god...there...just to people who believed in one.  Human life has value, why?  Simply because it's human life.  What a wonderful secular exclamation.  

You might say that is a distinction without a difference. It is not. That is why abortion and euthanasia are abhorrent to many theists.

-and also many atheists........

I'll say this again.  You, Steve, privately worry and publicly project that without a god, your god, you would fall into some sort of nihilism.  It's just you.  It has nothing to do with atheism, it does not follow from atheism...atheism....doesn't have a damned thing to say about the meaning of life, whether it has a meaning..or it's value if there is any.

The distinction is that a "no god" epistemology gives you subjective value/meaning/purpose which leave it open to a matter of opinion and a theistic epistemology provides objective grounding with God providing value/meaning/purpose which is not open to opinion or changing over time. 

If an atheist thinks abortion or euthanasia is abhorrent, then they must admit it is their opinion and other have a right to their opinion. Hopefully the "others" opinions don't matter more than yours when it comes to your baby or your grandmother. A theist has no such obligation to recognize someone else's opinion.
