Have you ever seen a fish cry ? And even if he could, how would it be possible for us to see it in his natural habitat ? At this point, this is not about the fact that he doesn't want to express his feelings, this is much about the fact that he can't do it, due to his environment. He is also the only animal which did not embark on Noah's Arch. This shows the true depth of his condition. It's the same for black people.
