What are the forms that religion …

Communalism : It means attempts to promote religious ideas between groups of people which are identified as different communities. Communalism can take various forms in politics :

(i) The most common expression of communalism is in everyday beliefs. These routinely involve religious prejudices, stereotype of religious communities and belief in the superiority of one's religion over other religions. This is so common that we often fail to notice it, even when we believe in it.
(ii) A communal mind often leads to a quest for political dominance of one's own religious community. For those belonging to majority community, this takes the form of majoritarian dominance. For those belonging to the minority community, it can take the form of a desire to form a separate political unit.
(iii) Political mobilisation on religious lines is another frequent form of communalism. This involves the use of sacred symbols, religious leaders, emotional appeal and plain fear in order to bring the followers of one religion together in the political arena.
(iv) Sometimes communalism takes its most ugly form of communal violence, riots and massacre.
