Like many, many religious Jews, I personally believe that no one can explain theologically why the Holocaust happened and that any attempt to do so is crass. G-d works in mysterious ways often incomprehensible to mere mortals. Again, apologize for your blanket libel of "the religious right" (we can hear the contempt through your monitor).
