Dear Michael,
It is not that Zizek hasn't got much to say, it is that he is coming from
one very dangerous school of thought called postmodernism. It is , of
course, more than possible that he has some valuable ideas and insights,
some exciting sociological ideas, but it is just something which is -
translated in political realm- very much unpleasant. I must say that I am
very much again postmodern to begin with. But po mo leftism is even more
dangerous than it's relativism in science.
  Regards,
         Andrej
