I remember once I had a woman come in who was really on the edge of a breakdown. She was talking about civil war and chaos, immigrants coming up the lanes of Sunderland with knives between their teeth to murder her. She was really in a terrible state. “I just said to her ‘What paper do you read, love?’ and, of course, it was the Daily Mail. I just said ‘stop reading it and you’ll find life gets better.’ That’s the only advice I could offer.

Nixon: I do not mind the homosexuality. I understand it. (14-second beep to hide personal information) But nevertheless, the point that I make is that goddamit, I do not think that you glorify on public television homosexuality… even more than you glorify whores. Now we all know that people go to whores. … we all have weaknesses. But, goddammit, what do you think that does to kids? What do you think that does to 11 and 12 year old boys when they see that? … You know what happened to the Greeks! Homosexuality destroyed them. Sure, Aristotle was a homo. We all know that. So was Socrates.

Ehrlichman: But he never had the influence that television had.

Johnson has always had a geek’s penchant for self-education, and in that spirit he cultivated a side interest, and ultimately an expertise, in writing computer code. His Web log, which he named “Little Green Footballs” (a private joke whose derivation he has always refused to divulge), was begun in February 2001 mostly as a way to share advice and information with fellow code jockeys – his approach was similar in outlook, if vastly larger in its reach, to the guiding spirit in the days of ham radio. His final post on Sept. 10, 2001, was titled “Placement of Web Page Elements.” It read, in its entirety: “Here’s a well-executed academic study of where users expect things to be on a typical Web page.” It linked to, well, exactly what it said. The post attracted one comment, which read, in its entirety, “Fantastic article.”

So should we tread warily, lest we are misunderstood? Of course we should. Cartoonists are some of the most painstaking, careful, shy and sensitive people on earth, yet we do play with fire, toying with other people’s (and of course our own) most deeply held beliefs and most cherished illusions. Is it possible to go too far? Of course it is? Should we go too far? Of course we should. That’s what makes our job so interesting. There’s no better feeling than, having taken a risk in a drawing, seeing the thing in print and knowing it works. The converse is also true, which is why I work in a bunker on the south coast.
