If Donuel is free to call a simple act of rather pointless kindness and expression of Godly qualities, why am I not free to say that is BullShit?

It is all in the context. I would use his example to point out the opposite of Godliness. A child at that sandbar might think he or she was playing God. An adult at that sandbar would think of how many fish wash up on all the sandbars of the world at any one time and realize how small that one little act is. A bear, or a hungry person is going to see that fish and think Food! Is the being that eats the fish Satan to that fish? I think not.

The fish, being a fish, is not contemplating God. The fish has no sense of creation or deliverance or good or evil. The fish is just going to keep flopping around until it finds water, or death.
