An Atheist is a person who questions every kind of authority, and this is the thing that is important. Because if we can, without blinking an eye, question the ultimate authority, god - who must be obeyed, then we can question the authority of the state, we can question the authority of a university structure, we can question the authority of our employer, we can question anything. So I think the primary thing that an Atheist is, is a person who looks at an authoritarian idea, or an authority structure, and says to that authority structure: from whence do you derive your authority and why should I be obedient to you? It appears to me that if I have human intelligence that this is enough for me to try to challenge whatever you're doing.
