I agree that we could find morally objectionable practices in most any culture. I think, however, that we would find many, if not most, of these objections would not involve the moral principle itself, but rather the application of the principle. For instance, in any justification for chattel slavery I have heard, the argument has not been that it is ok to own another human. It has been that the owned were somehow subhuman.
You should do more reading on this as slavery has a very long history outside of the US. And even within that context varying arguments existed including biblical justifications.

Furthermore, I'm not at all sure that an evolving set of ideals on morality is evidence against an objective moral reality. Our knowledge of the physical universe has evolved, yet we would not say that evolution corresponds to changes in the reality of the objective physical universe. We would say our understanding is more aligned with the objective reality. Why should I expect morality to be different?
Well that's just the thing. People don't use different math in asia, they don't have different physics in europe, different chemistry in africa. Yet there are different morals in all these places. I can demonstrate knowledge of the physical universe based on objective standards, you can't do this with morals.
Quote:
Neither can I prove the existence of the physical world beyond the existence of my own mind.
Which is a weak analogy. If I grant you a universe it's no issue objectively demonstrating scientific facts. Why when I grant you that same universe are you powerless to demonstrate moral facts? This same presupposition could be done for any subjective notion. You are special pleading for this one case where you want to pretend it's objective with no basis to do so besides your own emotions.

This was sloppy language on my part and obscured my point. It would have been better had I removed the subjective words and said "the sky is blue, chocolate has a taste, and roses have a smell."
Actually, you were accidentally more accurate than you meant to be because morality is felt, it's personal, it's subjective, that's why those things occurred to you. You can demonstrate those things as you've reworded them, you are unable to do so with morals.
To put it plainly in a moral context, the current words you are using are akin to saying "people kill other people". The previous words you were using are more like saying "it's wrong to kill other people". This is the is-ought problem. The universe only says what is, not what ought. You need an ethical principal to bridge the gap.
However, even removing the subjective language, it remains a fact that my individual experience of these

things will have a subjective component, as does any personal experience. When I experience these things, I am subjectively experiencing an objective reality. My point was that I trust the reality of these things based on my experience via the senses. Why is it any less reasonable to believe I am subjectively experiencing an objective morality via my internal sense of morality?
Because only one can be objectively demonstrated. And this is contradictory if we accept that your personal emotions are sufficient basis for reality. As I can find someone with different moral views with the same subjective strong emotions connected toward their own moral beliefs. What makes yours superior? We can't accept both as objective as they contradict.

Why is acceptance of our physical reality as we perceive it a reasonable baseline?
got a better one?
Quote:
Why not think that I am a brain in a vat?
This isn't a terrible baseline but it's worse, as it's less parsimonious. It carries all the complexity of the baseline that we exist in a real universe and adds in a vat, a brain, a universe to house the vat and brain, and something to create the vat and brain, and something to sustain the vat and brain...ect. Basically, you invented an extra universe with no call to do so.
Quote:
We trust our physical senses because we have no compelling reason to not do so. In other words, absent a true defeater belief, I am perfectly rational to believe that my senses are giving me a reasonably accurate depiction of my external reality.
What if when people looked around no one could agree on what color things are, how heavy they are, what shape they are? They all saw them different?
Quote:
What is the defeater belief that would prevent me from viewing my moral sense in the same way?
It's simple, you need only take two people, give them the axiomatic view that their moral sense reflects objective truth and see that they don't agree on everything. Also, there is dramatic evidence that your moral sense in malleable. Is that true with your sense of touch or hearing?
Quote:
Belief in Thor as an axiom is different than belief in the physical world and an objective morality as axiomatic.
Only one of those really.
Quote:
We clearly see evidence of an innate sense in humans that we live in a real physical world and that we are bound by a moral code.
Those two aren't the same, surely you can see how much weaker one is than the other? In fact, if you couldn't this conversation wouldn't be happening. We are sometimes bound by moral codes of our choosing. Evolution has evolved us with an innate sense of empathy and social bonds, we see these in other creatures incapable of moral judgment.
Quote:
What evidence is there that we as humans have an innate sense of Thor's existence?
This is, in fact, argued all the time by religions for their god. It's just as untrue as what you say.
Quote:
We can easily show evidence that society does indeed decide what rules of right and wrong they will agree upon and enforce. This fact does not bear on the existence of an actual objective morality any more than society agreeing upon which knowledge regarding the physical universe to pass onto the next generation bears on the actual objective physical universe.
Except one set of knowledge has an empirical, objective foundation. There aren't different scientific facts from one country to the next. Further, we can reasonably understand that humans have no innate sense of scientific knowledge, it's discovered. You are stuck arguing humans have an innate knowledge of objective morality. Why would this evolve? Why would it vary so widely from people to people from place to place? And even from person to person?
Show me this objective morality. Demonstrate it. You are arguing on pure unadulterated faith.
