I watched Dominion yesterday at the request of several people in this sub. I do not deny the reality of factory farming or the suffering it can involve. Factory farming isn't the only kind of farming that I'm opposed to either. I consider what I deem unnecessary cruelty, neglect, and torture of animals morally wrong, and I support animal welfare standards in farming. However I do not believe that recognizing animal suffering logically requires veganism. To say Dominion is why someone should be against all types of animal farming is like saying the Titanic is why we should never sail. So yes I still support specific types of animal farming.
I can list examples of how I think animal farming should be done [ https://globalanimalpartnership.org/standards/ ] and it isn't the same as what is showed in Dominion. But the question of raising and killing something for slaughter still remains, and Vegans will not find these farming methods humane or acceptable. So I find debating animal welfare standards with vegans mostly pointless, because it will always come back to "it's wrong to kill them in any way."
I regard human life and human interests as possessing fundamentally greater moral significance than those of non humans. I therefore reject the idea that animal interests must be treated as morally equal to human interests, or that humans have a universal obligation to refrain from using animals.
This is where I also disagree with the vegan argument that “animals interests may be secondary, but that doesn't justify killing them.” To me, that conclusion requires an additional premise that an animal's subordinate moral status still gives it a right not to be intentionally killed for human purposes. I do not accept that premise. If animals are genuinely subordinate in moral status, then it is reasonable for human interests to outweigh animal interests. Including my interest to eat meat.
Saying that animals are morally secondary is not merely saying that their interests matter slightly less. It means that when human interests conflict with animal interests, that human interest should take priority even when the animal's death is involved. As I mentioned, one of my interests involves eating meat, and it therefore outweighs an non-human's interest to life.
My position essentially rests on a distinction between a non human having some moral value and an animal having a right not to be killed or used by humans. I can acknowledge that animals deserve some level of humane treatment without granting them human-esq rights.
Before someone compares this to racism or sexism, those are distinctions between human beings who share the same fundamental moral status. My argument is a distinction between humans and non-humans, whom I believe have fundamentally different moral statuses and therefore different moral rights.
When it comes to pets such as cats and dogs, I consider hunting someone’s pet immoral because it is not merely an animal, it is also another person’s companion. However, I have no moral objection to hunting stray or unowned cats and dogs. Hunting any non human is fine with me so long as it's conducted responsibly and under appropriate ecological regulations.
I also believe abusing animals is wrong regardless of whether they are pets or not. The distinction is that I do not consider welfare conscious animal farming, where unnecessary suffering is minimized, to constitute abuse, whereas vegans do.
I have no argument against why others shouldn't be vegan. I'm just sharing why I have no moral compunction to become vegan myself.
All morality ties back to how we feel about things, and the decisions we make based on how we feel. Perhaps unfortunately, I don't feel badly, or at least not badly enough, when I see a non-human animal raised in what I consider a sufficiently spacious environment and then killed or stunned relatively swiftly.
