Mark's comic and the CFIDS diet comic both made me laugh. But I agree that the diet comic is unsuitable outside our community, and I'm not sure about Mark's. That is what's going on, but we need to prove it, but that's not that hard to do, I think just accompany with some research papers might do the trick.
Mark, if you added in the biomedical research to the drawing and deleted the last frame, then it might work. (also I assume you would draw the final version on unlined paper) And I don't understand whether the one lady is pushing a pram? or is that supposed to be a walker? If it's a pram I think that's unnecessary info. If it's a walker I would situate it closer to her.
Mij, I don't know if this will make you feel any better, but I can't tell you how many times girls I know have told me they wish they had food intolerances or whatever I had, so they could be thin like me. I would tell them they didn't know what they were asking for--being underweight causes problems. They never quite believed me. (By the way, my weight is ok now)
Esther, your drawing is amazing. The message is perfect and you should absolutely sent it to the New Yorker. In fact if you would like to collect signatures to send with it like a petition, I will sign.
