The decision by PEN American Center to give its annual Freedom of Expression Courage award to the French satirical newspaper Charlie Hebdo has prompted six writers to withdraw as literary hosts at the group’s annual gala on May 5, adding a new twist to the continuing debate over the publication’s status as a martyr for free speech.

The novelists Peter Carey, Michael Ondaatje, Francine Prose, Teju Cole, Rachel Kushner and Taiye Selasi have withdrawn from the gala, at the American Museum of Natural History in Manhattan. Gerard Biard, Charlie Hebdo’s editor in chief, and Jean-Baptiste Thoret, a Charlie Hebdo staff member who arrived late for work on Jan. 7 and missed the attack by Islamic extremists that killed 12 people, are scheduled to accept the award.

In an email to PEN’s leadership on Friday, Ms. Kushner said she was withdrawing out of discomfort with what she called the magazine’s “cultural intolerance” and promotion of “a kind of forced secular view,” opinions echoed by other writers who pulled out.

Mr. Carey, in an email interview yesterday, said the award stepped beyond the group’s traditional role of protecting freedom of expression against government oppression.
