Iconoclasms are not always an act of rebellion against one's own religion but in most cases an act of protecting their religion's ideals, read further for clarification.
2) Someone who rebels and attacks against traditional or popular ideals.
"Uproar began in the Islamic community when the prophet Muhammad was graphically depicted in a Danish publication. Calls for the image's destruction were never ending but when they went unheard some in the Islamic community resorted to becoming iconoclasts themselves and publicly burning the newspaper in which the image was published."
It was kind of difficult to fit the noun into a sentence without starting with "an iconoclast is..." so please make do with this sub-par usage sentence for now.
From the Medieval Greek "Eikonoklastes" - "Eikon" meaning image and "klastes" meaning breaker thus "image breaker." It was around 730 when this word originated during a period of the Byzantine Empire in which Icons or Images depicting religious figures were taken and destroyed. It was first recorded in English in 1641in reference to this period of time ( the Byzantine Iconoclasts).
