That Gawker regularly vent their unsophisticated spleen on Katie Roiphe may be thought a reason to read her books. Much of the other invective that streams towards Roiphe appears to be a result of her mid-90’s polemics on campus rape.
I don’t know if this was the case during those debates, but Roiphe does seem courageous enough to argue against the grain in In Praise of Messy Lives, though in this case her target is conventional marriage and parenthood, and what, if any, putative advantages a nuclear family confers on a child compared to single parenthood (roughly half of all first children in the US are born to unwed mothers). Ropihe’s arguments are eloquent and convincing, but rarely stray beyond the confines of a narrow bourgeois demographic.
In Praise of Messy Lives also includes some entertaining pieces of literary criticism including a contentious defence of the US literary old-guard’s (Roth, Updike etc.) depiction of sex, compared to its vapid portrayal by the following generation (DFW, Franzen etc.) My favourite of these essays is the study of the depth of Joan Didion’s influence on later American women writers. Apart from a feeble essay on Jane Austen, Roiphe fails to acknowledge any writing outside the US, but this insularity that blights American literature is far from isolated to Roiphe.
For a flavour of Roiphe’s style I can recommend this superb article: Want To Understand Sexual Politics? Read This Novel. There also a good NYT review of these essays.
