 All of scripture is open to interpretation, but since fundamentalism builds off of interpreting scripture as solely literal, and that's the only way, isn't much room for looking at it as literature, as poetry, and interpreting it as possibly metaphor. A common accusation that so-called progressive Christians will try to use against regular Christians is that we take the whole Bible literally. I don't know where these people are getting their information from, but this couldn't be further from the truth. Jesus referred to himself as the door and the lamb, but none of us are expecting him to baaah. Isaiah talks about God being the potter and us as the clay, but the Bible's not trying to tell me that I'm a vase. The real distinction here is that we take Genesis' historicity seriously, as well as Jesus' historicity, while some try to disregard with certain aspects of the Bible because they don't align with their ideological commitments. Don't let somebody shame you by saying you take the whole Bible literally. It's not true.
