It is important not to domesticate Jesus' social passion. 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 famework of a domination system. He was a critic of the domination system itself. Indeed, that's the best explanation for why he was killed. He wasn't simply a nice inclusive fellow but a religious social prophet whose teaching, behavior, and social vision radically challenged the elites and the domination system of his day.
