You are being pretty vague. Are you now suggesting animals don't have emotions or can't form bonds with humans? Do you want proof in general or in this specific case? What would be an example of proof?
And once again, please offer proof to your statement that pigs form bonds with farmers and it is the ultimate betrayal to the pigs' trust when they are eventually put down.
I am not being vague at all, it's pretty clear what I'm asking for. I am not suggesting anything nor forcing views on somebody ... I merely want explanation and some sort of proof to the very bold statement you made. I am not talking about animal emotions or bonds with humans (which I do believe some animals may be capable of). Rather, I'm look for anything that talks about the apparent bond of trust between farm animals (cows, pigs, chickens) and the farmers. Bonus points are awarded if it discusses the tragedy behind breaking this bond and the betrayal that is mutual to all parties. You have posted plenty of articles on this thread on other statements you have made (though most have not been sufficient proof of your argument), I can't imagine this would be met with much more difficulty if it is indeed true as you claim.
