Temple Grandin is highly respected by those of us who raise livestock. Here is a quote from her website:
I think using animals for food is an ethical thing to do, but we've got to do it right. We've got to give those animals a decent life and we've got to give them a painless death. We owe the animal respect.
I really like that OHG. I'm a vegetarian, but I don't have any negative thoughts or ill will towards meat eaters (personal choice 'eh). Besides, my husband eats all the animals and I love him. I really like "We owe the animal respect.". Nice thought.
