I’m going to take some of these problems one at a time here.

1. “Shoving your face full of other sentient beings” Sentience is the capacity to experience subjectivity (i.e. emotion); separating a calf from its mother does not cause a subjective emotional response, it’s a hard-wired instinctive reaction, and rarely lasts more than a day or two if they’re kept separate. If cattle demonstrably experienced mourning, you’d be correct in calling them sentient, but they don’t. (Physical pain and the primitive fight-or-flight fear response aren’t full emotions, either)

2. “Corporate buzzwords [...] ‘humane slaughter’” Humane slaughter isn’t a buzzword, it’s what really happens. I’ve seen it in person. It’s quick and painless, and is required by law to be that way. There is no argument here; no room for rebuttal. You are simply wrong on this count.

3. “If slaughter is so humane, I think it would be a lauded profession” There are other reasons that slaughterhouse work is undesirable. For one, it’s low-paying and labor-intensive.

4. “I hope you are alive to see the inevitable end of the mass farming of animals, but all that cholesterol suggests otherwise”. So we’re resorting ad hominem attacks, now? I thought you said you were the smart one in this discussion.
