So true. The Bible says that we are created in God's image and that God gave us domain to do whatever we like to animals... just so long as we don't attempt to copulate with them. It should be a crime to even hint that an animal's life could be valued as a human life... Except for my trusty dog companion. </sarcasm>
Sorry if I actually subscribe to that belief. Neither did God give humans a free pass on torturing less valued species. Animals are given as a resource much like trees and oil. Animals also happen to have some capacity for emotion and intelligence. Since they are similar to us in some way we should respect them, lest we become callus with the taking of intelligent life.
As for pets, it's a cultural thing that we don't eat pets. The bible cautions against following culturally aberrant activities provided doing so doesn't infringe on your service to God.
I would hope you will have some respect for other peoples' beliefs in the future.
