I can think of lots of worse people to worry about. A man who has sold millions of books is hardly secretive. Yet, he does need to control his message. especially from green eyed monsters who would do him in.
If the message is the mobilization of 1 Billion Christians to solve all the worlds ills; and, yet, he hides the data center that those Christians are supposedly to use from public eye and protects it more than a lot of defense sites are protected - I don’t care what anyone says, it is odd.
