Since the small racists are innumerable, sometimes we need the big racists to attack or destroy the small racists, in order to end racism everywhere. As a matter of fact, the big racists will inevitably taste and swallow their own medicine. This is the big fish, small fish theory. Remember George Corley Wallace Jr., the former Governor of Alabama, during the Civil Rights Movement of the 60'S.
There isn't any symbolism. The sea is the sea. The old man is an old man. The boy is a boy and the fish is a fish. The shark are all sharks no better and no worse. All the symbolism that people say is shit. What goes beyond is what you see beyond when you know.
