If it needs interpretation, then it's not literal FK. That's what literal means.
We are not going to get into that "depends what is the meaning of 'is'" legal obfuscation thing, are we?
No, there is no need to be legalistic, it is just what the word means. You seem to reject some correct meanings and usages of the word. I used the word "literal" to mean "actual". Any linguist will tell you that is perfectly correct. I just believe the Bible contains the actual words of God, not filtered through fallible men. How else could the Bible have any credibility? Jesus is clear that some of God's actual words were meant to be interpreted, such as parables.
