Willie,These are your exact words: "What is literal is literal, and what is metaphoric is metaphoric. But no one has the right or the authority to create fantasies by spiritualizing away the Scriptures." Are you now going to say that when the Bible DOES NOT say something is "The Antichrist", we can take references we find, and declare they mean "Antichrist?"
If you would rather call him the Man of Sin, feel free. Ever since the Reformation this man has rightly been called the Antichrist, because he opposes Christ and also comes in place of Christ. That is the meaning of *antichristos*.
