Is that really tolerance? All you've done is expanded your in group. You could still be just as intolerant of your now slightly smaller outgroup.

That's how it's always been. We've extened our in-groups from family to tribe to city state to nation / religious group to (for some) all of humanity. But we still put billions of intelligent, feeling animals through a lifetime of pain so we can eat them. Perhaps in a few centuries the umbrella of inclusion will be broad enough to protect all mammals.

The arrow of history flies toward larger and larger in-groups but humans have always been horrible to those they label as "other".
