Secularism means that religion is something subjective that must be confined to an individual's private and family life, and religious feelings and ideas should not interfere in the socio-politico set-up, be the concern of nationalism only. So the socio-politico roots of religion should be severed from politics. Nationalism leads directly to secularism. The belief that national unity must be based on a common land, race or language, necessitates that religion be kept apart from politics.
Thus, secularism paves the way for the domination of nationalism, since according to this school of thought, religion and nationalism cannot rule at the same time in the same realm. Secularism is the twin brother of nationalism and it changes the meaning of minorities. In a government founded on religion, the followers of other creeds and schools are regarded as minorities, but with nationalism and secularism, there are only racial, political and regional minorities.
Nationalism claims that religious beliefs prevent national unity and religious minorities feel themselves alienated. The only proper basis is geographical, racial or lingual nationality. The main duty of everyone is the patriotic duty, and religious duty is subordinate to it, and confined to personal belief. The patriotic duty of everyone is to sacrifice everything, even religion, for the nation and country and serve and fight for them.
Basis and other characteristics of Nationalism Nationalism considers sovereignty as a tool to protect the country and its citizens, not one for enforcing a particular ideology and system. Economy, too, is based on national interest and welfare, not on what is legitimate or illegitimate. Culture, art, poetry and literature are the means for depicting national pride and greatness and creation of solidarity and inspiring racial sentiments.
To nationalism, the strongest factors directing individual and social life, determining intellectual and political postures, are the country and nation. As Ibn-Khaldoon says, the element behind patriotism is nationality. Some of the other characteristics of nationalism are: Belief that one should defend a compatriot against a foreigner, whether the former is in the right or not. Eulogizing and almost worship of national personalities and historical heroes of one's country.
Revival of past traditions such as ancient idolatry.
