Without being too harsh with Dolphin, Dresser cites medieval legends, compares the actual symptoms of the various forms of porphyria, and thoroughly explodes Dolphin's hypothesis. Dolphin proposes that porphyria sufferers have adverse reactions to garlic; Dresser gets information from doctors indicating this is false. Dolphin proposes that porphyria sufferers could find relief by drinking blood; this is also false. Dresser also reveals that Dolphin's ideas of vampirism come mostly from the image of the creature constructed by Bram Stoker, and not from pre-existing legends.
But the most interesting part of this chapter, which makes this to me a profound book and not merely an informative one, is Dresser's discussions of porphyria sufferers who were ostracized or mocked by friends, family, and coworkers as a result of Dolphin's hypothesis (a result Dolphin hadn't anticipated). Although most of the examples Dresser cites of people making jokes about porphyria clearly meant it to be harmless, it isn't harmless to those who have the condition. This has led me to a resolution to change the way I discuss disorders--of any kind--on this blog or elsewhere. Even well-meant jokes can sting when people are suffering. I think of some of the ways I've discussed homosexuality in previous posts and am not much pleased with myself.
Also, I'm inclined to say I wish I had read this before Snuffles, Lucky, and I had written our review of Twilight
