It's a given that fundies believe the bible is the inspired Word of God. I was talking to an Episcopalian guy that didn't believe the bible was without error. He did what you are doing and considered the natural process of translation and book selection and concluded it was untrustworthy. This nullifies what the bible says in the same way that Pharisees made the commandments of God of no effect with their traditions.
If one beleives the Bible to be untrue then they beleive Christ is a liar and did not send the Holy Spirit. If they think that they're not Christians.
