i haven't really thought much of the arguments criticizing pope benedict XVI for his "nazi past." there's plenty to criticize about the new pope, but nazism is such an inflamatory charge and implies that ratzinger himself was himself a nazi in the true believer sense--something i do not believe he is.
but jeanne d'arc makes a compelling case the ratzinger's failure to acknowledge the issues surrounding his past raises a real question of his present ability to take responsibility for his own actions, or at least be answerable for them.
you may not agree with her argument, but it's well worth reading. and, at the very least, she raises issues that should be addressed by anyone who wants to argue that the pope's nazi past is not relevant or important today.
