No they are fragile people in need of guidance and support.
They believe they found those in religion

Do I believe that religious people are gullible? Damn, that question just about answers itself.

Not necessarily. The issue is childhood indoctrination. A lot of religious people aren't stupid, they just have a really hard time questioning something that has been drilled into them from birth. Honestly it's not an easy thing to overcome.

I think they are gullible when it comes to the bible and religion, yes. Religious people can be very logical and/or skeptic in other aspects of their lives and dealings.

DUUUH!

Can’t check any of the three options. There have been, however, some very intelligent religious people—Einstein for example.

IMO the most meaningful dichotomy is not between theists and atheists but between those with the courage to evolve in their understanding and those with fixed, immutable opinions, frozen by fear and ego.

Not certain if they are gullible. However, I feel they turn to religion because the NEED something to believe in when they can't simply believe in themselves or other folks.

Religious people don't always blindly believe anything, but they are definitely more susceptible to irrational ideas, in my experience. I believe religious people are more gullible on the whole than non-religious. They are taught not to question.

Gullible ? No more than anyone else.
They are willfully ignorant more than nonbelievers though.

They are not inherently more gullible, they are indoctrinated at a young age and taught to believe what cannot be proven. Unfortunately this form of thought does carry over into other aspects of their life.

Not guillible.The majority of Religious people were Indoctrinated In to a religion from birth . This has nothing to do with being guillible it has to do with being brainwashed

They can't be categorised very easily. I think people try to psychoanalyse them too but I don't think that works either. And what about people like me who used to fervently believe in god and don't anymore? I think the sincere ones are aspiring people who get caught up in group-think. The ones who are raised in a religion are completely bound up in the mentality of family and congregation members. Nonetheless, even some of them find the spirit to question and leave.
