Perhaps by now—if not within minutes or hours—most discussion of George Zimmerman’s acquittal for shooting Trayvon Martin, an unarmed black teenager, will be crowded from the news cycle. What on earth could be more compelling to Americans than serious talk about the role of bias in jury deliberation, or gun laws and cultural codes of firearm manliness, or voting rights, or who really gets to stand their ground in America?

Remember Rizzo from the movie Grease? The indomitable Stockard Channing played a smoldering hottie who rivals the perky Olivia Newton-John. We recognize the split: Betty Rizzo struts her T & A. Wholesome Sandy flaunts perfect teeth.

Back in the day Rizzo was called a slut, a word that even sounds dirty. Leap forward thirty-five years and we’d be her cheering squad. Sure, Rizzo boasted a fine rack and leaned toward the uncouth, but like today’s female protagonists, she had moxie and smarts. Think: Jennifer Lawrence in Silver Linings Playbook. Think: Katniss Everdeen in Hunger Games. Think: Lisbeth Salander in The Girl With the Dragon Tattoo. These characters have more in common with the brazen dames immortalized by Crawford, Stanwyck, and Davis than they do with the kittenish Newton-John. Fifty years ago, in The Feminine Mystique, Betty Friedan inspired women to stash their aprons next to their brooms and see what else the world offered. How would the prophetic Betty have reacted to what Elizabeth Hand calls the new Femininjas?
