I think that anybody can be right about the Bible even if they are biased because the Bible itself was written by biased people. Who would understand it better than other biased people? It seems strange, but in court you have a prosecution and a defense to present their sides. You don't have unbiased people, each side has a goal, and it is not necessarily the truth, but it works in the end because each biased person has to deal with the other side's arguments. I think unbiased people are also less motivated to come up with ideas because they are not worried about the topic as much. Biased people are constantly trying all kinds of new usually crazy and desperate arguments to defend their beliefs or attack other beliefs, but sometimes they might be right. I know that religious Bible scholars are not open-minded, but I also think atheist Bible scholars are not open-minded. We are all closed-minded, but we don't know it. That is why we have to accept bias in this subject.
