The Religion of peace (sometimes abbreviated as ROP or RoP) is a political neologism used to describe Islam. After the September 11, 2001 attacks some politicians described Islam as a "religion of peace" in an effort to differentiate between Islamic terrorists and non-violent Muslims.[1] Subsequently, some critics of Islam have adopted the phrase, using the term "The Religion of Peace" in a sarcastic manner as a synonym for Islam.
