Shortly after the Berlin Wall fell, someone at the school where I work put up a picture of Ronald Reagan talking with John Paul II. The picture was posted on the faculty lounge bulletin board. For historical reasons, of course.
Well, that offended someone else, who took the picture down. But the original poster had made many copies of that picture. So when one was torn down, another one was put up. Eventually the offended party gave up and the picture remained.
I wonder who that original poster was? :)
