"Secularism in current usage is generally the ideology that certain practices or institutions should exist separately from religion or religious belief. Alternatively, it is a principle of promoting secular ideas or values in either public or private settings.
In one sense, secularism may assert the freedom of religion, and freedom from the government imposition of religion upon the people, within a state that is neutral on matters of belief, and gives no state privileges or subsidies to religions. In another sense, it refers to a belief that human activities and decisions, especially political ones, should be based on evidence and fact rather than religious influence."
"In political terms, secularism is a movement towards the separation of religion and government (often termed the separation of church and state). This can refer to reducing ties between a government and a state religion, replacing laws based on scripture (such as the Ten Commandments and Sharia law) with civil laws, and eliminating discrimination on the basis of religion. This is said to add to democracy by protecting the rights of each religious minorities."
