@layman,
So, right under that, there is a link to this page:
http://nobeliefs.com/freethinkers.htm
Turns out that, when you go there, you get a bunch of material from "famous" writers, such as Thomas Jefferson, Robert Green Ingersoll ("known as the Great Agnostic because of his antireligious views"), Bertrand Russell ("He realized that the Christian religion, as organized in the churches, "has been and still is the principle enemy of moral progress in the world'), Daniel C. Dennett, and Richard Dawkins (two of the most strident and most militant atheists on the public stage these days).
I wonder if those authors are held up as "authorities," eh? SURELY not.
But I suspect that if I would just absorb and digest their teaching, and their wisdom, I too could be a "freethinker," ya know?
Then again, maybe not. Given the website name (nobeliefs.com) you get the idea that these people simply have no beliefs. Nothing to tell you.
