In the early Medieval period the word meat just meant whatever you had as a meal, things you ate rather than just drinking.
Also mince meat pie in some capacities is just fruits and nuts and spices, no animal flesh (though I do think there's a version with bone broth that's still not chunks of flesh).
My grandparents called the liquid inside a coconut as milk, not water or juice.
I think, on some level these people must realize it's objectively weird to rape animals to treat them like machines and they don't want people thinking too hard about how strange and perverted it is...even Native Americans who hunted or fished found animal agriculture strange and sadistic. I read this article in an environmental law class from the 1930s, where a tribal leader talks about an animals right to live a free and natural life before death. A more recent article I read describes the mythology of native people being simple savages who only hunted and gathered, while in California at least they tended wild plants like a garden, aside from doing controlled burns, their methods of land management were highly sophisticated in relation to local ecosystem health and the animals who live there. This article uses terms like land rights as well as animal rights, which is pretty profound. They mean the rights of the land, not to the land.
So yeah these commercial ag businesses must realize on some level it's bizarre and unnatural which deepens their attachment to culturally familiar, safe or "normal" words.
Or maybe they don't. But I was reading a Guardian article about humane cows milk the other day and it gave me the creeps. The dairy farmers calling it "their milk" really brought home how rapey and sadistic it is, as a mindset, to raise animals for commercial purposes. Maybe not the Hindus and their family cow that they raise naturally with nursing calves, but any commercial dairy.
