Since you sound interested I'll give you my take. I work in tech but I do it as an evangelical missionary. I think I'm not too far outside the norm (as much as there is such a thing) for an American protestant. Of course the answers to your questions can vary pretty widely based on who you ask but that leads me to think you might be interested in hearing from more than one person.

1.) The boundary of my beliefs - in terms of people offending me by what they say or write - I really don't care and don't get offended. I have zero expectation for people who don't adhere to my beliefs to say things in line with them. If another person who is a Christian says things I think are really out of line, it wouldn't offend me but I'd try to engage them and work it out - but people who don't believe in it, I don't expect to act like they do. If a person who is of another faith or an atheist is interested in discussing something like the validity of the Bible, I'm happy to have that discussion as long as it is a real discussion. If it's a debate with us just mindlessly exchanging arguments, I have better things to do.

2) I don't think IT and religion are at odds in any way. The tension happens more at the level of your next question. IT is too far removed from those fundamental questions. In fact, as someone who's life is focused on sharing a message with as many people as possibe, IT is awesome.

3) This is trickier. If something is for sure a scientific fact and it conflicts with what I believe my faith teaches about the nature of the world then my assumption is that I've somehow misunderstood what my faith teaches. The only authority I recognize for this is the Bible - so to simplify the discussion - if a fact contradicts what I believe the Bible says then I assume my understanding of the Bible is wrong and I adjust. For your two examples - coming to understand evolution and fit it into my faith has been an on-going process for me over a lot of year. The Big Bang is something that fits my world view better than one that proposes God does not exist.

4) Same as above but I think that a lot of what people believe to be "historically proofed facts" about the Bible are in fact wrong and reflect a lack of information with regards to current knowledge on history. A lot of theories about when parts of the Bible were written and who wrote them rest on the bias of the theories authors rather than any facts. For instance I believe the New Testament was written by people who knew Jesus Christ, saw what he did in person or knew people from that group. I do not think it was written much later by people creating a religion.

If I were to find out something I believe to be true is absolutely false - I would evaluate and adjust. I've done it in my lifetime. It's something I do about more than just my faith. My politics have changed during my adult life and lots of beliefs I have, have moved as I experience more and learn more. I've been living in Europe for 4 years, for example, and in that time I've changed my mind about lots of things. It has been a real education. I don't cling blindly to any opinon. I don't mindlessly follow any 'leaders' teaching or instructions.

Hope that's the kind of feedback you are interested in - if you want to continue the discussion feel free to email me if that's easier than here - bittercode@gmail.com
