"Its roots [of the term 'communalism'] lie in the British colonial policy of taking “communities” as the relevant units in recruitment or in the allotment of seats in representative assemblies. Originally, the term had no pejorative connotation, but Indian nationalists in the freedom movement objected to these “communal” policies which allegedly aimed at keeping the Indian population divided. Indeed, the biggest worry of the freedom movement was the “communalist” collaboration of the Muslim League with the colonial administration: in exchange for “communal” electorates and recruitment quota, the party claiming to represent the Indian Muslims agreed to stay aloof from the anti-British agitation. Today, “communalism” is one of those labels allotted exclusively to people who reject it; it is a term of abuse. Even people who advocate communal recruitment quota (a demand recently revived by an array of Muslim organizations) are now self-described “secularists” and signatories to every new “National Manifesto [...] Against Communalism.... Jamaat-i-Islami (whose Pakistani wing has campaigned for decades, and with success, for the desecularization of the state) attacks “communalism” in the name of “secularism”. I cannot recall a single issue of the Islamist papers Radiance and Muslim India which failed to brandish “secularism” and denounce “communalism”. ... Imposition of an exonym, especially a pejorative one like "coummunalist", must be considered a statement of involvement in an anti-Hindu-revivalist or so-called "anti-communal" crusade..."
