Islamophobic stereotypes persist through historical repetition regardless of accuracy [causal]
When confronted with the commonality of Islamophobic themes of the fanatic Muslim man, the oppressed Muslim woman, and an intolerant Islamic religion, defenders of these views often respond that their prevalence must reflect their truth. After all, they argue, all stereotypes have some seed of truth. The ironclad quality of this tautology—that past repetition of an allegation is justification for its reiteration—recommends a different tack in refutation. A historical evaluation of these claims that demonstrates their persistence despite historical changes helps demonstrate how the core of American and British Islamophobia derives from received truisms that have established—and continue to establish—basic expectations about how Muslims behave. These expectations shape how information about Muslims is interpreted so that what fails to fit within this frame of reference (e.g., Muslim tolerance, nonviolent Muslim protest) often is overlooked.
DEFINE: Explains how a tautological defense of stereotypes works: their repetition is taken as evidence of their truth.
