At a conference entitled “I Am My Brother’s Keeper: Confronting Islamophobia” held at St. Mark's Episcopal Cathedral, Seattle on May 6–7, 2011, Christison stated that “The discourse in this country at the moment is very Islamophobic” and that the “anti-Muslim discourse,” is driven by “pressure from the pro-Israel lobby and Islamophobia lobby."
He was a signatory to an intellectual letter from 38 Muslim scholars, sent as the official Islamic response to Islamophobic comments made by Pope Benedict XVI on September 12, 2006.
