Metaphors

On the subject of the reading, I'm beginning to have less sympathy for the negative assumptions of WC's, given the metaphors that scholars use. To name a few (not only from this reading): clinical/medical deficiency, mental health probelms, manure, 1984/ "Big Brother"... none of those conjure positive images in my mind. And while the explanations of the metaphors (usually) make sense, one would think that something a little more cheery could be constructed by people who study rhetoric for a living.
