There is definitely bubble wrapped around theists in their own religion. Ask an average people what they know about a given religion and they would either say they don't know or would give a grossly inaccurate response. I came from a pre-dominantly Catholic culture, and my parents don't even know what makes Protestants different to Catholics. I had to tell them that Protestants simply don't believe in the authority of the pope. And then there was a pastor telling me to "just believe" in just about anything, after I stated I am agnostic atheist. He mentioned everyone believes in a religion, like how Muslims believe in Muhammad, or Buddhists believe Buddha is a god. And I was like, no, Buddhists don't believe Buddha is a god-- he simply was a human being believed to have attained enlightenment.

It is many of those instances I realised people are generally ignorant and have pre- and misconceptions. Not only that, even way before the idea of post-modernism, people generally want to stick with information that comforts them, whether intentional or not.
