The recent celebration of Ramadan sparked one of the largest increases of anti-Muslim incidents in more than a decade. In Joplin, Missouri, the Islamic Society’s building was destroyed by fire under suspicious conditions. A bottle of acid was thrown at a Muslim school in Lombard, Illinois, while worshipers were saying evening prayers. A mosque in Harrisonburg, Virginia, was desecrated with anti-Muslim graffiti. The number of anti-Muslim hate groups tripled from 2010 to 2011. Forty-three percent of Muslims experienced some kind of harassment during 2010–11 (Center for American Progress, September 26).
