I guess it's inevitable that any woman who approaches the U.S. executive office is going to be called Wonder Woman, including Sarah Palin. However, many people, including Lynda Carter, have expressed dismay that Palin is being compared to Wonder Woman and see her as undeserving of the name and what it represents.
I thought I would offer some recent textual evidence from Wonder Woman #20 to highlight the differences between Palin and Wonder Woman on one issue in particular: the treatment of wolves. Without getting too graphic about it, Palin supports the aerial killing of wolves within her own state, Alaska. The practice is said to be inhumane because it can extend the animals' suffering in death.
In the story "Ends of the Earth," written by Gail Simone, Wonder Woman is first stalked and then attacked by wolves. Wonder Woman addresses the wolves directly in the above panel, saying, "Hunters of the claw and fang, I beseech thee. Do not die this night. Go. Leave!"
When Wonder Woman realizes the wolves are diseased and unable to respond according to their instincts, or "animal reason" as she calls it, she uses her lasso to calm them. In response to the wolves' request to be released from their agony, Wonder Woman regretfully kills the pack with her sword out of mercy.
I like this part of Simone's story because it illustrates Wonder Woman's beliefs and, to my mind at least, makes them plausibly consistent with an all-female culture such as the Amazons. Of course, that doesn't mean that men can't love animals or that some woman aren't barracudas.
