Unfortunately I waited too long to edit a response to your edit, so I have to engage in the discourtesy of double posting. :)

> There is plenty wrong with causing suffering.

What, specifically? What makes it wrong?

> I think in the case of eating animals, society is quite detached from the experience, though. That's why we shy away from watching slaughterhouse videos, why we put pictures of happy cows on cartons of milk - why such an unbelievably rosy picture must be painted to justify ruthless and horrific violence taking place all the time.

For millions of years, most people hunted down and slaughtered their own food. In many cases the animals suffered horribly, even as badly or worse than they do in our industrial farming environments.

I agree that most people are far removed from the experience of the suffering and killing of farm animals. I think that's exactly why people like you exist. Most people are raised up surrounded by puppies and kittens, not food animals, and grow up watching Disney movies full of friendly, talking animals. The majority of modern western society is far removed from the reality of life. No surprise that when confronted with excerpts from it, they respond with horror, it being utterly at odds with their prior experience.

> To the same point, the reason it is acceptable to raise and kill billions of animals are also social norms and culture. Is the hypocrisy of it all not apparent?

No. There is no larger moral framework. Morality is a social phenomena that manifests in arbitrary ways, though with humans (as with other social animals) it will always tend to some degree of in-group altrusim. There is no hypocrisy to be had because it is fundamentally arbitrary.

> It's appalling you don't recognize that not abusing sentient creatures is morally superior

This is my point. Our culturally contextual blinders generally prevent us from coming to objective conclusions about right and wrong. There is no objective right and wrong. There is no telescope science can use to inform us about moral reality. There are no sacred laws inscribed on our souls by God. Innumerable philosophers have tried to ground morality in something objective and all of them failed. This is why you keep repeating that the suffering and killing of animals is wrong, but cannot explain to me why this is so, except that is appalling that I need an explanation. It is a reality for you, insofar as it is a reflection of your feelings and tastes, but your feelings and tastes are not my feelings and tastes nor at they anyone else's; they are yours alone. History is the single best teacher of the subjectivity of morality.

There's nothing wrong (in my opinion) with having the feelings and tastes you do (and therefore the moral-philosphical positions), but you cannot convince me, or people like me, of your position by stamping your feet and asserting a moral superiority that not only does not exist but cannot exist.

> Personally, I see this as a strong denial mechanism which you may be yet unaware of.

My moral nihilism, or whatever you might choose to label it, came to fruition long before I had the vaguest idea of defending the eating of animals. Nor do I feel particularly strongly on the subject; if a law was passed tomorrow I would chiefly be annoyed at the difficulty of getting the protein/calorie ratio demanded by my workout and diet regimen.

I am not interested in the documentary, having seen plenty of examples of gratuitous animal cruelty myself, and having killed animals (legally) myself. There is no amount of suffering that a video could show me that would change my mind because I deny that the suffering is inherently wrong. I merely prefer that the suffering of animals be minimized to the extent that it can be done without raising the cost of meat significantly.
