Toss up between Bill Maher and Jim Jefferies.

Really Carl Sagan, but so many had already said him. Every little bit helps.

I just reposted that image on my pinterest page.

Carl Sagan. He made science fun and human, gave a great perspective, outwardly as well as inwardly. He is one of my heros.

I like carl sagan and richard feynman. they were funny and intelligent and caring, and how can you not like a scientist who wears a headband while playing bongos and chanting "juice juice juice, orange juice"? how can you not like a scientist who goes into detail about the fate of hypatia, and makes us feel as if a foremother of ours was murdered -- and make us cry, too, for the library of alexandria? and they didn't preach their atheism. they didn't preach. they taught us to see the world as it is. the fact is, that's a world without god, and clear vision shows that. their clarity shows that. they didn't have to say it.

Carlin, Nye, Tyson, Fry, Penn, and The Amazing Randy.

I like sceince because you can test it ask questions about it and never go to hell for not so in favor of some of the things it says

Also the bible is written like the first lawyers so you can cherry pick things to prove some stupid point

number 3 yes of course #4 of course stolen from other legends and fables 5 too The rumor is Jesus is a comglamortion of several people at the time.

There simply way too many to list.
But I can say that favor those who do talk about anti-religion, and yet are huge proponent of Reaching out to people about Science, and critical thinking.
That to me is more important than just bashing religion.
Dawkins, Tyson,Krauss,Nye, Thunderfoot, PZ Meyres.
just to name a few.

Don't get me wrong, I do love Those who fight the good fight so to speak in regards about Atheism.
Hitch, Harris, Darkmatter2525, Dillihunty, Carrier, and many others.

Is Bill Nye a terrible answer, LOL? I'm a science teacher, and I just love listening to him get annoyed at people when he talks about creationism, abortion, dinosaurs, etc.! I really don't pay attention to anything related to religion in the world.

I wouldn't call him a role model, but James Randi is who I first started reading when learning about scepticism.

I don't have one. I probably need to read more about it. When other people answer I will look up who they read. I just don't car enough about God and religion to read about it much.
