Name one company that meets your theoretically consistent ethical standard of never killing or harming an animal, even incidentally. I don't think there are any.
I don't have that standard. There are perhaps a hundred food retailers in the city where I live that meet my ethical standards, out of perhaps 1000-2000 in total.
My standards for how to treat animals don't depend on whether I eat that animal after it's died. "Can maltreat as long as I don't eat it" is IMO difficult to justify.
Okay. My ethical standard is "to exclude — as far as is possible and practicable — all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose."
You'll note the wiggle room. It's not about being perfect and never contributing to animal harm because that's impossible. It's about doing the best you can in a bad situation.
