I have yet to see an actual literalist. Try to confront one you suspect, and ask them about shellfish. The bible condemns eating shellfish as "an abomination" on par with homosexuality. Or ask him about mixed fabrics clothes. Again, bible says it's not allowed. No, the only Christians so far are cafeteria Christians - No death and doom ideology for me, I'll move over here to the "love your neighbor" line, ignoring the very next passage and just taking what I like.
There is no such thing as a literalist, because they would not be able to function in today's society.
