It might be interesting to consider that there is more than one personality in an individual. I'm not talking schizo...but there is the group personality that might sound a lot like it's just following the crowd...and that occurs in all areas. One can hardly exclude the group peer pressure of a church or religious institution. I'm sure it might happen in an atheist group.
Then there is the individual personality. One never knows exactly what THAT persona actually believes. A person need NEVER actually fess up their true feelings and beliefs.
I am sure, that at times, I jump on the bandwagon concerning some aspects of god beliefs I find particularly odd and even repulsive. I might overstate and exaggerate. But inside, I am pretty sure I'm honest with myself and harbor doubts about...almost everything I think I know.
Anyone...Christian theists or staunch atheist should always retain a bit of humility in the light that we none of us can know everything. But generally my, perhaps biased, perspective is that the theists more often than not are the ones who claim certain knowledge about a vast number of things I absolutely know for sure they CAN NOT know. They are the ones who make a point of using faith and what they think in their heads as evidence for things and a solid basis for gaining knowledge and finding truth.
