Wolfgang's point of view is protected by freedom of speech. His messages have been reasonable and respectful. As DougR stated, "getting carried away" is not necessary in responding to Wolfgang. There is no need to censor him or to characterize scientists as having a different code of honor.
This weekend I am going to a conference on illustration and science. Art and science both uses processes of exploration, questioning, discovery, and problem solving. There is much to be learned from what Wolfgang has written if the defensiveness would be put aside. He is not attacking anyone, he is expressing his considerably well educated and experienced opinion.
