> "Even though I see them as livestock, not pets" Isn't it funny how this is a completely arbitrary definition? The most sensible explanation I've seen about this phenomenon is called carnism and it's brilliantly explained by Dr. Melaine Joy in this TED talk: https://www.youtube.com/watch?v=o0VrZPBskpg
No, it's not arbitrary at all, it's just subjective and depends on your personal relation with the animal. Frankly, that video sounds like BS to me. How much time did she spend within family farms that raise animals? The idea that you need "invisibility" or to abstract animals as non-individual or as objects is so untrue it's not even funny.
I have no idea if she has spent time within family farms, but I would guess that she, like most people versed in animal rights, would strongly disagree with exploiting the bodies and reproductive systems of animals unnecessarily. Regardless of it being done in a factory farm or in the best family farm, where animals roam free until the day they are sent to the house of slaughter, at a young age.
If you sent a perfectly healthy dog (or horse, or cat, or elephant) to slaughter, for profit or pleasure, in a culture that sees those animals as members of their moral community, you would get a very different reaction from society.
