Editorial cartooning is an inherently negative medium. I have read tens of thousands of political cartoons. I have never encountered one that was positive — one that praised someone or something (never mind whether or not they deserved the praise) that wasn’t horrible.
The purpose of an editorial cartoon is to scream on the page, or screen, to wake up a complacent populace to injustice. It’s true, if injustice went away, I’d be out of work. Which would really be great.
