I agree with you, theology101, that feedlots and the like are dismal places, indeed. Driving past them is bothersome to me. It gives me a very defined feeling of sadness, and sometimes anger. I don't believe God intended them to be treated that way. And you are certainly on to something when saying that people who mistreat animals could easily do the same to humans. When I see people abusing animals in the ways in which you described, it makes me wonder if their interior life is also filled with violence and anger. It would seem that way since our actions flow from the interior.
I think the thing that displeases me so greatly about animal rights people in general is the amount of sentimentality and anthropomorphism that is displayed within the group. It seems as though they put animals on the same level as humans, and reality (God) clearly says that it is not to be so. Beasts are subject to us, and of course we should tend to them, and treat them as we should treat any of God's creation, but these people take it too far. My family raised all of our own meat, and we took diligent care of our livestock. We kept them on healthy pasture, gave them adequete shelter, etc., but my parents always made sure that my sister and I understood that they were livestock, not pets. To drive the point home, they would name our pigs things like Bacon, and Porker, lol. This way we knew that they would ultimately end up on our table, because that was what they were intended for. There was no sobbing and pleading when the day came to take Bacon to the meat lockers this way.
