I think what bothers me the most is that when I, as a Christian, try to relate my experiences or beliefs (to unbelievers, in particular), mostly all I get in return is a bunch of arguments against my beliefs. Why can't people, anyone, just accept someone's belief? If my beliefs aren't immoral or illegal or offensive to anyone (and I can honestly say that I never intend to offend), then why do I have to receive such criticism and critique? Why can't a believer's beliefs just be believed? lol
We speak differently in the courtroom (i.e., more formal) than we do with our family and/or friends (i.e., less formal). The context provides a framework which provides rules to govern how we are expected to interact with others or behave. Allow me to provide an example.
The local courthouse has a sign hanging on the wall outside the doors. It expressly forbids, with threat of contempt of court, wearing baseball caps inside the courtroom. However, the local baseball team has no issues with your wearing a baseball cap. The different context provides a different framework or rules which govern how we behave.
So, what does this have to do with your questions? Well, most discussions on the Internet fall somewhere between a strict formal (i.e., well defined set of rules for interaction) and a wholly informal (i.e., no clearly defined rules) context. Thus, on Internet forums, you have a mixture of people who come with a mixture of different expectations. These expectations influence how they will interact with you, and how they expect you to interact with them.
With regard to CF.net, there is more formal expectation that one support and defend their perspectives within certain areas of the message board, and less formal expectations elsewhere. This, being the Apologetics and Theology forum, will naturally come with more formal expectations of providing "external" defenses because it is difficult, if not impossible, to "see" the truth or validity of something without having a reasonable presentation as to how we can see this. The General Discussion forum does not generally carry this expectation. (Well, that would depend greatly on the participants.)
With regard to non-believers, it is important to remember they do not share many of our beliefs and so they do not start from the same viewpoint that we do. Hence, this is why it's necessary to seek common ground from which we can discuss issues (i.e., a common starting point). (That's why I find the "atheism is the default position" notion to be absurd.) We cannot assume God exists, and then proceed from that assumption. (That's merely an example. I do not mean to imply all non-believers here are atheists.)
Of course, this is precisely why I think many people botch the notion of burden of proof. They think people must "absolutely" prove -- redundant, I know -- all claims all of the time. That's absurd. Burden of proof is a socially constructed and contextually defined concept.
Anyway, I am digressing. That's my understanding of the social interaction on the Internet in a nutshell, and that's why some people are unwilling to merely accept a believer's appeal to belief.
