The significance of the twelfth chapter of Revelation is understood the same way the first eleven and the last ten will be. Come to the text with a plain understanding of the previous 65 books of the Bible. Read the text as a whole before coming to conclusions about it. And understand that the actions and attitude of our enemy aren't the focus of the book. It's the Revelation of Jesus Christ. Any attention given to our enemy should be taken in order to make Jesus all the more glorious.
