What is secular society?

Answer 1

A secular society is a society that runs on a non-religious basis. In other words, legislators and government officials are generally barred from imposing laws or policies with the intent of furthering a particular religious agenda. Also, religious considerations do not overrule the civil legal structure. Overall the legal, legislative, and administrative processes in a secular society operate independently of any religious beliefs whatsoever.

A secular society need not be actively anti religious, however. It must simply maintain a separation of powers between the religious establishment and the civil institutions. Indeed, some consider a secular society to be better equipped to protect the equality and freedom of all contingent religions, because no single faith is given a primacy of influence in the structure of the society.

Addition

Good examples are generally the Western European nations where religion is personal and separate from politics. This is in theory the United States but obviously not. A secular society is primarily to keep a majority religion/set of beliefs from persecuting another and therefore in theory keeps any religions from gaining the power and backing of the government.
