What would you consider moral norms? I would say yes, many agree that say killing and stealing are wrong... but those things fall under the golden rule-- treat others as you wish to be treated-- this is the basics of living in a society. There are some things, such as cannibalism, that we consider to be wrong whereas others find to be the norm.
Very seldom is cannibalism ever practiced. In fact the exceptions when they do occur prove the rule, as rationalizations are made like "they weren't really human" or when it is done, it is done during periods of emergencies or as a terror tactic, then not done anymore.
You in fact picked a good example of a universally held taboo.
I wouldnt kill them and steal there stuff... but i dont see where this has to do with the possibility of innate morality... i see it has more to do with commonsense and logic, and again, the golden rule.
But how does one justify the Golden rule? Also not everyone knows about it. Many in fact would see the above as wrong without knowing of the Golden Rule. Or logic.
(BTW how does pure logic show us that murder is wrong?)
The Golden rule seems insufficient, as people practiced morals for a long time after before the Golden Rule was established. And the Golden rule is merely an abstraction, I reject it, but then why would I still feel bad about doing certain things?
Does one simply not have a conscience until one hears about the Golden Rule?
The Golden Rule lastly is merely an abstract concept, but there are emotions connected to morality, not just thoughts. So again the Golden Rule hardly serves as a foundation, let alone a sufficient one.
As for common sense I agree, but I'm getting more specific. I am saying why it is common sense, and just what sense we are talking about.

Haha maybe it would be simplier, but if i was looking for the simpliest answer, i would just say "God did it."
No you wouldn't because God would be a new type of entity. And explaining things by means of a new entity is not parsimonious as explaining things via entities we are already aware of.
Also that wouldn't even answer the question. the question keep in mind asks why would you feel bad even if God told you to do it?
Saying "God did it" would not even make sense.
Condemnations from you and I, but at some times and places in this world incest in certain societies has been accepted as a norm.
Yes but you are failing to realize that if it is just a matter of belief, why is it you
feel bad about it, when you don't believe it? Simply saying "Because I live in a christian society" is not sufficient, because you reject the belief (i.e. think it is not true), so you then shouldn't feel a nasty reaction when violating the norm if the norm is merely an abstract thought.
Secondly, incest taboos like cannibalism are also one of the most universally upheld things among humans, among all mammals even, especially mother-son incest. In fact you are far more likely to find a society that's ok with theft, rape or murder, then one that's ok with mother-son incest.

While evolutionary theory predicts a certain level of parent-child and sibling rivalry, its predictions are contrary to another mainstay of social science--the Freudian Oedipus Complex. Under evolutionary theory, fathers have a strong vested interest in their son's well-being; provided, of course, it is their son. As sons mature, they may in fact compete with their fathers for status and for females (as daughters may compete with their mothers for males), but not for their own mother (or father). Many evolutionists argue that, given the decreased viability of children born out of incest, selection has created an incest taboo, especially against mother-son incest. The comparative ethnographic data support the existence of the incest taboo, not the Oedipus complex.
And where incest is committed it is again one of those exceptions that proves the rule, as it is only done for extraordinary reasons, like keeping power.
It's like any other instinct, can you find instances where it is ignored? Yes. Almost in every society. Catholic priests refrain from sex, Hindu followers sometimes abstain from eating, certain people for health benefits refrain from sweets, certain parents don't love their kids, certain people cannot see because they are born blind.
But do these exceptions by themselves disprove the notion of innate behavior?
No. Just because a behavior is innate does not mean it is inevitable. Evolutionary psychologists have abandoned that line of reasoning a long time ago. Environment for example plays a strong role, as do beliefs on how to satisfy an innate value.
Also there isn't really as neat a divide as one might think between instinct and enviroment.
Take height for instance, such is undoubtedly influenced by genes, but keep that man half starved and he will never reach his full height.
Likewise obesity is influenced by genes, but put that man in a third world country and he will not get obese.
So even if a behavior is innate, it can be influenced a great deal by enviroment, beliefs, and other motives/innate behaviors.
A case of the third example would be if I could eat poisoned food. I sure may be hungry, I sure may want food, but my survival instinct this point may outweigh my innate desire to satisfy my hunger.
