I know right now I'm talking to myself, but I just asked a question which would probably be flagged as 'off topic' because I didn't ask a question 'about Christianity' I just asked a question that wants a Christian answer and Christianity is well known for attempting to answer.
So rather than asking, "How does your faith in Jesus give your life meaning?", I ask "What is the meaning of life?" Which in this venue ought to mean the same thing.
However, this doesn't fly on the other SE sites. On programmers.SE for instance, I can't ask "What is the meaning of life?" I can't even ask "What is the meaning of programming?".
However, this site is not a site for "professional Christians", so perhaps it'll be more lenient.
