Once upon a time—say, ten or even five years ago—a Liberated Woman was somebody who had sex before marriage and a job afterward. Once upon the same time, a Liberated Zone was any foreign place lucky enough to have an American army in it. Both ideas seem antiquated now, and for pretty much the same reason: Liberation isn't exposure to the American values of Mom-and-apple-pie anymore (not even if Mom is allowed to work in an office and vote once in a while); it's the escape from them.
For instance:
Barnard girls move quietly, unlasciviously into the men's dorms at Columbia; a student sleep-in to protest the absence of "rational communities"—co-ed dorms like those already springing up at other universities.
Wives and mothers march around the Hudson Street alimony jail with posters announcing they don't want alimony.
A coven of 13 members of WITCH (The Women's International Terrorist Conspiracy from Hell, celebrating witches and gypsies as the first women resistance fighters) demonstrates against that bastion of white male supremacy: Wall Street. The next day, the market falls five points.
More witches and some black-veiled brides invade the Bridal Fair at Madison Square Garden. They carry signs ("Confront the *****-makers," "Here Comes the Bribe"), sing, shout, release white mice in the audience of would-be brides, and generally scare the living daylights out of exhibitors who are trying to market the conventional delights of bridal gowns, kitchen appliances, package-deal honeymoon trips and heart-shaped swimming pools.
