I think the CH cartoonists see what they are satirising and mocking as disgusting, vile, sick, etc. That's the point that a lot of people don't seem to get. You aren't supposed to 'like' the cartoons or to find them amusing. They are supposed to disgust you, but the disgust is supposed to be directed at the subject of the cartoons, not at the images themselves.
I am speaking from a position of detachment here, having not seen many CH cartoons. They are not my style. But I think I understand their purpose, their aim. I would probably dislike them as intensely as anyone on here, but I get the point. Seems a lot of people don't.
