Meanwhile, please check out Clone.Manga. The humouristic strips are some of the most offensive ones I've ever seen and obviously morbidly fascinating just because of that - just look at the story of poor Nana. However, the more serious work (Kanami, Penny Tribute, Paper Eleven) is beautifully drawn and the stories are fascinating, if violent.
The thing that makes me want to draw attention to the page at this moment is the author's ending two of the "humorous" series with a joke about 9-11. Predictably he got a load of hate mail as a reward, and his open response to that (just scroll beneath the top image) is absolutely wonderful. The hate mail he received for joking about 9-11 is symptomatic of much the same hypocrisy that makes me fret every time a natural catastrophy happens. Essentially, people seem to put various bad things on a scale of how upsetting they are, and this scale is in no way related to how horrible the events ACTUALLY are.
Just like people care more for the tsunami and Katrina victims than the people who die daily from starvation and AIDS, they are more likely to be offended if you joke about 9-11 than infanticide or the holocaust. And THAT offends ME.
