If you believe in talking snakes and winged horses that can fly you to heaven you are very gullible.

They are simply being real. That is all. No tricks to it. You have not offered a better, testable explanation. Until you can your comments are just blabber. Sorry my friend, to be so blunt.

Warren Buffet, Donald Trump, Mark Zucherberg, Bill Gates, and Jimmy Kimmel all eat at McDonalds. Therefore, eating at McDonalds will make you rich and famous.

Combative atheists resort to name-calling and demonization out of weakness.

Open-minded atheists engage in civil discourse and search for understanding and common ground.

As such there is a built in gullibility in all humans, as this is part of the way we learn. Then around the age of 9, we begin the journey of discovery and can form our own view of the world around us.
There are many studies into conformity to look at which can give researchers a direction of study into why we follow religion.
I find it very interesting when looking at local Christian groups the differences in how they practice. I was at an Evangelical church on Sunday, where they have a simple fun message put through using many of propaganda styles of the NAZIs. Very effective unless you can stop and think. None of it stands up to scientific or historical scrutiny. Oddly I see lecturers from college there as active members. I go because of work duties (plus they have some of the best coffee in town). Then there is hell-fire and damnation crowd that bother people on a Saturday morning in the town centre where they sing slightly out of tune boring hymns interspaced with a preacher telling everyone that they are filthy sinners who are going to hell. After all, their parents had sex and sex is a sin. All rather mad if you think about it.
One group using inclusion and generates an enemy (that's me!) and has fun. The other employs fear and subjugation. Both produce human 'sheep' who should not think or question, but must follow the rules of 'god' which is administered by the priestly classes.
I questioned this Christian God from as far as I can remember from about 8, then became an atheist just before turning 14. Attending church only reinforces my scientific views.

Dawkins and Dennett are very smart men and both have an excellent command of the English language.

"Gullible" is the perfect word to describe one who is easily persuaded. It's not a pejorative term.

I was gullible at an early age; that's what we are when we're young and I'm fine to admit it. I carried religious belief for years, due to the early imprint.

There's a post from you, almost daily, regarding definitions. You're welcome to post what you wish, but seem utterly confused about your beliefs, which is evident here, yet again. Or, you're dogmatic about your perspective being the correct one - again.

The word "gullible" is simply honest, as it's used by Dawkins. We could all stand to be a little more honest, with each other and ourselves, don't you think?

Religion may be an evolutionary advantage for interaction of the group similar to Richerson & Boyd. (Swaab, D. 2014)
