High Quality Content by WIKIPEDIA articles! The religion of peace is a political neologism used as a description of Islam. After the September 11, 2001 attacks, some politicians described Islam as a "religion of peace" in an effort to differentiate between Islamic terrorists, islamism, and non-violent Muslims. Subsequently, some critics of Islam have adopted the phrase, using the term "Religion of Peace" in a sarcastic manner as a pejorative synonym for Islam.
