Read the Pew Forum on Reigion & Public Life 2012. The most knowlegable in religious teachings of all demographics ?
Yeah sorry to annoy you, its obviously a survey with satanic bias..... it was the atheists and agnostics. To you that may be confusing, to me it makes perfect sense.. and here is the issue.. PERSPECTIVE.
Firstly, atheist is a religious term. There is no word for people that dont believe in unicorns and fairies. Also how much info do you have on Zeus? Do you believe in Zeus? Do you think that everyone that does not believe in Zeus has the same knowlege that you do on Zeus?
Religion puts people in boxes, much like your awful chart. If you are a JW you dont believe in evolution because that has been dictated to you. Sorry to make things a little complex for your box of generalisations, but when you leave religion (call it atheism/agnosticisim if you wish) you are free to know and believe what you wish.... scary hey... all that freedom.
I have never been so informed in al my life (I suggest a trip to google scholar if this appeals to you, but be weary much effort is required, it is very easy, I mean lazy, to let other people think for you..) I get all my knowlege from the sources themselves, no brooklyn filter required.
So as you can see, two JW's fit nicely into a box..... two atheists would not share a box, they would walk freely between the boxes arguing with all the people in the boxes. Peering over the box lid "hey buddy... what you doing ? Are you worshiping HIM ?.... you know he is based on a mesapotanian myth right?" and.... "hey you guys, stop handing out those magazines, did you know that the factory that made them has just been fined for dumping toxic waste in a water drinking source?"..... etc etc....
