Good points, Eric. And your questions are difficult to answer. Let me put it this way: Am I biased? Absolutely. And I struggle to make sure I am doing my best to be aware of and step outside that bias when needed, and to constantly evaluate my position. There is a delicate balance between being fully convinced and yet retaining an open mind. I try to do both, sometimes more successfully than others.
If I seem frustrated, I don't mean to. I do sometimes get impatient debunking the same arguments over and over. And, yes, if the gospels were frauds, I would want to know. I am convinced they are not to the point I have gone against my upbringing and stakes my life on it, as you mentioned. But it would be silly to stubbornly insist on continuing if they are not true. But, again, there really isn't any evidence I have seen that they are frauds, and I feel that the vast majority of reasons that are brought up to suggest that they are are exaggerations or unsupported leaps in logic.
EDIT: Eric, I will also say that if you detect frustration in my posts at times, a lot of that also comes from the tone of the posts I am responding to. I know that whatever someone else says and how they may say it are not excuses for me to lose patience. But it's a lot easier to respond to a posts with the tone yours have than...some others.
