The idea that the term came from non-religious people, or secularists, is just wrong.
I wish you would stop using secular in place of atheist. It simply does not make sense, particularly in this subject. The anabaptists... as religious as they were... were secularists.
Yes, if we are discussing something outside of gov't practices then secular would indicate a nonreligious item, but when discussing gov't practices it means only that gov't is nonreligious in the sense that gov't is about earthly matters alone, and church is for spiritual matters.
It is not a "religious tenet", which is to say one must be religious, to believe in such a separation and there have been those outside religious communities which have promoted that idea. Neither must a person be atheist to believe in secularism IN GOVT.
This test definitely scores you some points that history is getting poorly edited. What's ironic is that you don't seem to mind where the test is right and fundies are doing the editing. The founders were generally religious and secularism was a movement within religious communities, and the nation was founded on secularist principles which means it is not founded on a religion.
