We live in an age when you can prowl the streets of major cities and find human beings offering themselves in store windows, or just reach for the yellow pages and have them delivered. It is the same mindset at work, spreading in our world, and after a while this attitude can find nothing very special about anything or anybody, let alone whales.
The point is not that Jesus was a good guy who accepted everybody, and thus we should do the same (though that would be good). Rather, his teachings and behaviour reflect an alternative social vision. Jesus was not talking about how to be good and how to behave within the framework of a domination system. He was a critic of the domination system itself.
