But compassion toward all living things is more of a tenet of Christianity than of any of the other major world religions. At least we don't make a ceremony of slitting the throat of a goat during our major festivals as is standard practice in Islam.
These people have far too much time on their hands and far too little grey matter to figure out what to do with it.
For most people, I'm not sure that choice has anything to do with it. It's a matter of body chemestry. We are omnivorous. Those canine teeth in our mouths aren't decorations. God made us to eat both meat and vegetables.
I love all animals. However, loving animals will not force me to make some goofy quasi-moral choice to bow out of the food chain. MEAT. It's what's for dinner.
