Atheists in church

[Spongebob]

I've had scores of conversations, discussions, debates and such with Christians on the subject of what constitutes and supports their belief. I maintain that it is largely emotional in most people and largely due to years of indoctrination and family/community pressure, making most people emotionally reluctant to veer far from the religion of their youth. But in almost every case, people reject this notion and argue that their belief is based on rational decision making, even critical thinking. If this were the case, there should be no reason for Christians to be wary of atheists in their midst, asking challenging questions. Such discussions should only result in strengthening their faith. But of course the true reason such strengthening occurs is because of the defensiveness that is ignited when someone challenges your beliefs.
