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 behavior 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.
