Well that gets proven every post.
But if one had the courage of their convictions, if one really believed in their faith, if one was proud of their beliefs and had nothing to hide the question I would ask is why would you NOT want to answer any and all questions abut your faith.
I know I would and do often when asked.
More over why is the concept of NOT answering everyone's questions being taught to those who are going out to professionally sell your religion that is supposedly the only "true" one.
DECEPTION!
