There has been some similar a discussion regarding this topic, so please forgive me and close this if the same question is asked elsewhere. However...
Please explain if I am incorrect in this logic.
If I go to programmers.SE or stackoverflow.SE and ask a question about programming, I expect those questions to be answered by programmers about programming.
'How do I solve specific programming problem XYZ, using C#' This maybe answered by someone solving the problem using perl, lets say, not what I was looking for in the question exactly, but could be informative anyway. A perl programmer answering a programming question about C# is still a programmer. I would be surprised or upset if someone like a ballerina instructor answered the question saying that maybe I should be dancing instead of programming all day.
Similarly, if I ask a question on Christianity.SE should I not expect the answers to be from people who at least claim to be Christian, or answering from within a Christian context? If I answered a question from Math.SE, even though I am not a mathematician, I would answer the question from a mathematical context. If I answered a question on math.SE saying that numbers don't really exist, I'd get kicked out, or voted down at least.
Now, there is a huge diversity of christian beliefs certainly, and this should be fully acknowledged and accepted. However, if someone (no matter their world view) wanders across Christianity.SE and asks a question, only to get a bunch of non-christian responses, how confusing would that be?
I say that various denominations/traditions on Christianity.SE are analogous to different type of programmers (languages/methodologies/etc) on SO. I could be a non programmer who needs to do some trivial scripting in Excel or something, who asks a question on SO, and that would be completely valid, and I would expect answers from people who knew what they were talking about. Conversely, if I was the same non programmer I might not be answering too many question on SO, because I am not the intended audience that the questioners had in mind when asking their question.
Another analogy might be this. I'd LOVE to have my atheist friend come to my (non-church affiliated) bible study, and I would LOVE for that person to ask a ton a questions. But, I might not want that person to come to my bible study and teach?
Do these analogies hold, or am I completely off base?
