"Secularism allow anyone to be a cannibal. While sectarianism want everyone to be a cannibal. Be secular. Keep your mythology in private. Enjoy your meal in private in this secular world. Among who drink human blood and eat human flesh are catholic church and episcopal church." - Byron Pojol
Sectarianism, according to one definition, is bigotry, discrimination, or hatred arising from attaching importance to perceived differences between subdivisions within a group, such as between different denominations of a religion, etc.
Secularism is the principle of separation of government institutions, and the persons mandated to represent the State, from religious institutions and religious dignitaries. In one sense, secularism may assert the right to be free from religious rule and teachings, and the right to freedom from governmental imposition of religion upon the people within a state that is neutral on matters of belief.
