There’s a good reason we’ll never see an end to the battle of the sexes. Talking about it is just too damn fun. Hanna Rosin, senior editor at the Atlantic and co-founder of Slate’s DoubleX blog, stokes this ongoing debate better than most. After she made the case against breastfeeding, she moved onto bigger targets, writing a deeply controversial piece for the magazine called “The End of Men.” In it, she echoes the argument made by Campbell Scott’s character in Roger Dodger, who says that men will eventually be reduced to a life of servitude. (Rosin trotted out that line of logic again in a Sept. 2 cover story for the New York Times Magazine called “Who Wears the Pants in This Economy?”) Since the Atlantic article ran two years ago, Rosin has developed “The End of Men” into a full-fledged book, which she brings to Sixth & I Historic Synagogue tonight. David Plotz, her husband, editor of Slate, and former City Paper senior editor, will interview her. There’s no doubt it will be a lively discussion, with probably at least a few people in the audience wondering whether Plotz feels emasculated by his apparently inevitable uselessness. Then again, others still might think, “Rosin can write a book about the end of the men, but it doesn’t change the fact that her husband still has the power to fire her ass.”

The discussion begins at 7 p.m. at Sixth & I Historic Synagogue, 600 I St. NW. $12. sixthandi.org. (202) 408-3100.
