This was not the author's complaint. If Islam does get a pass by the writers of Time, then your criticism would be valid. I don't know what Time magazine has written about Islam, since I would never waste my time (pun intended) reading it.
The mainstream media is more intent on denying the divinity of Jesus than they are in examining ALL of the works of Alfred Kinsey (who in their eyes was a cultural hero).
If Jesus was not divine, there is little to examine about His life. He would be just another man and a pretender to the throne. If He IS divine, it is the single biggest event in the history of man.
