Let me rephrase, I found nothing disgusting or alarming and nothing that couldn't be broken through with reason and logic in that article with the superhappy people and the babyeaters, however I realise that they were both anthropomorphised quite extremely, because they were human constructs to start with, if you note, the babyeaters are looked down on, and it's no coincidence that the superhappy people were feared.
Maybe it's all the star trek in me but I want to believe in the natural goodness of social beings, and I find it hard to believe that non-social beings would be able to evolve to a point where their technological prowess would allow interstellar spaceflight, moreover, all these things are far more grand than some crappy "we do **** cuz some 'greater being' we can't explain or anything threw some rocks at us with crap scribbled on them".
Moral codes arise from observing positive or negative reactions (in the surrounding environment) to ones actions, or now, words.
A unification of our species moral compass will happen, eventually. It's also likely to happen with any alien cultures we might encounter, eventually, given enough communication and shared ecological(probably more likely, economical) environment(s).
As it stands our species is slowly drifting towards what the west currently generally perceives as 'good' - equality for all and aspirations achievable by all, but the reality is far from the ideal, and more often than not it's self inflicted.
