The first half of my argument wasn't ethical, it was practical. Regarding my statement that I doubt we know everything there is to know about nutrition, what could possibly make you think we know everything?!?
I don't think we know everything. But that argument works as well for me as it does for you. You say we don't know what nutrients we need from vegetables. I say we don't know what harms meat is doing us. So, I don't see how this stands up as a reason to prefer meat eating to vegetarianism.
And surely even you would admit that all animals (including humans) have the right to eat the food they need to be healthy and thrive?
Apparently, humans don't need meat to be healthy and thrive. Millions of vegetarians around the world can attest to that.
Rights are a social construct invented by intelligent beings to make their interactions more efficient and mutually beneficial.
Well, yes. A right is a recognition of an interest that is enforceable (usually by process of law).
They are based on our nature as thinking beings with free will and our ability to abide by a social contract.
But human infants apparently have rights, as do mentally disabled people. Is that because they can abide by a "social contract"? I don't think so.
It is natural for us to protect the young and the weak among us. We do this as part of the social contract knowing that when we were young, our parents protected us; and in the hope that when we are old and weak others will again protect us and care for us.
And why does this not extend to animals over which we have guardianship, in the same way that it extends to humans over whom we have guardianship? Please explain what makes the difference.
There's nothing I can really do to help you "get over" this deficiency, I don't think. Either you can see that you owe a duty to other creatures with whom you share the planet, or you can't.
I see no deficiency. I see your way of thinking as weak and overly sentimental.
Might makes right, then? Hmm... Sounds like a fairly typical conservative stance.
I'm guessing you're probably not an environmentalist, either. Why should you care about what happens to the Brazilian rainforest? Or, if you do care, it is only because you worry about the possible effects on yourself and human beings you care about. You owe no duty to the forest itself. It is just a thing, right? It has no intrinsic value. Am I wrong?
Nope. You're pretty much correct. I would lament the loss of the rainforest only for the loss of possible drugs and products that could have come from it. And, or course, the natural beauty that would be lost.
The natural beauty is only valuable in that you might get enjoyment from it, though. It too, has no [enc]intrinsic value[/enc].
Do you ultimately evaluate the value of everything only in terms of its utility to yourself?
If I needed to kill every spotted owl in existence to save the life of one person I cared about, I wouldn't even hesitate. I do not support needless cruelty to animals, but I value human life infinitely more than animal life.
I have never argued that if it came to making a choice between saving a human life and saving an animal life that it would necessarily be wrong to choose the human above the animal. But in choosing not to eat meat, you do not put your life (or the life of any human being) at risk. And in choosing to eat meat, you put the lives of countless numbers of animals at risk, needlessly.
