I think your understanding of my reply is not correct. I have zero problem with animals killing other animals for food because it very typically is the only way they are able to eat and survive. I have read about (over the years, I don't have any sources) animals killing for "fun" or without eating their kill. I would have a problem with those cases.
> I think we’re basically in agreement: there is some problem with wild animals eating other wild animals.
We are not in agreement. I do not think there is any problem with wild animals eating other wild animals.
> Terminology aside, predation clearly involves unnecessary suffering.
I disagree with this. The suffering is necessary for wild animals. If lions could eat antelope without causing any fear or pain to the antelope, that would be nice - but these species have evolved in opposition to each other so there is no other way in nature for the lion to eat the antelope other than to catch it and kill it, which unfortunately causes suffering. As a human, I am more able to catch and kill my prey with minimal suffering, which is nice. I don't actually know if animals suffer for any length of time after being shot in the head, but if they do, it is reasonable to think that it is sub-second in duration. Sometimes things can go wrong, and suffering lasts longer. That is to be avoided.
> The only part I find curious is that where I would call that “a slight moral force”, you would call it “morally neutral”. Why is that? Why does the question “do you have any problem with this” make sense to you, when it sounds like you agree there is a self-evident — though nuanced, and relatively minor — problem?
I am not following you here I think. When I said "Killing animals for food I find morally neutral," I mean I have a right to eat and the animal has a right to survive. Those interests are in opposition. As far as hunting, given a fair chance - sometimes the animal will win and sometimes I will win. This is neutral to me. As far as farming there is an exchange - I provide food, shelter and protection for a short while, the animal provides me with nourishment. This is also neutral to me.
> Speaking for myself, I certainly do have far less issue with eating an animal that I can be personally assured has only had “one bad day”. I don’t think animals care that they live in a cage, iff the cage is big enough; in fact, they probably prefer it. This opinion is overwhelmingly common among the other vegetarians I know. Those who dissent are generally worrying about other less-humane-seeming things such as premature separation of young from parents— and those concerns are always tempered with the acknowledgement that it’s still far more humane than the common practice.
This sounds like you would not have a problem running your own farm and eating your own livestock. If you are able to take the enormous responsibility of animal husbandry seriously, it can be hugely rewarding and fulfilling.
