h/t Rev's Rumbles
A literalist is someone who says everything that could be taken literally in the Bible must be taken literally.
A fundamentalist is someone who says if you are not a literalist, you are not a Christian and if you say something in the Bible could be taken metaphorically when it must be taken literally, then you are against God.
If you are against God, you are evil.
