Who are these “some on FR” you refer to? I haven’t seen anyone more concerned for animals than humans. I’m thoroughly disgusted and heartbroken by what happened to Shaniya Davis, but that doesn’t mean I have to support beating piglets and gassing them until they’re almost dead then gawking at them while they slowly die. That’s not my idea of entertainment.
I’m sorry, but there really can’t a credible defense of animals UNTIL long after human issues are solved.
According to the Bible, those in God are stewards of animals, nothing more. Subsequently, those who are not in God are not under even that rule.
