Is [your belief] it the product of fear of hell? Disappointing god or your family? What drove you to believe what you believe and furthermore, do you think this is a good reason for you to hold on to belief?I can only speak for myself. I was motivated because of a search for the truth. I was dissatisfied with the answers that my assumptions that atheism was continually pushing me to. It gradually became harder and harder to justify not seriously considering belief in God. Right across the board - from questions about the universe, why there's something rather than nothing, why the universe should be ordered the way it is, to the seemingly totally unrelated subject of identity and morality, where I found no good atheist answers. It seemed that belief in God provided far more substantive answers and made much more sense of the world.
For me, Christianity came after many, many sleepless nights of thought, reading, considering... I wasn't after religion or even God in particular, I was after the truth.
I think I share you dislike of trying to socially engineer beliefs (or disbelief). There is a much more commonly used tactic to socially condition people though. I humbly suggest that making fun of people, aggressiveness and rudeness are tools used to shortcut real consideration of the issues. It's hardly possible to stand there and calmly and carefully consider an issue if someone is launching into a tirade of aggressive and loud mouthed ridicule. The most likely response is to keep their mouth shut and their not mention their thoughts for fear of being laughed at or ridiculed.
Ridicule and overly aggressive rhetoric are not valid tools to use to persuade people. All they do is drive these real issues from people's minds - and socially condition them to avoid the topic. Unfortunately they are all too common, and I think both atheists and certainly Christians should not be using them.
