Petra is a world Heritage site and world class tourist attraction. Jordan is fiercely proud of Petra and the Nabetean heritage it represents.
To make the assumption you made is ludicrous.
You're right.
The Muzzies would never deface a world class tourist attraction that contains religious imagery that might be interpreted by some as idolatrous.
They learned their lesson real good when they destroyed thousands of churches and their associated mosaics, statues, stained glass windows and relics throughout the Middle East. They also learned their lesson when they plastered over the walls of cathedrals such as Santa Sofia. And they learned it when they destroyed Buddhist statutes in Afghanistan and India. And again when they wiped out Hindu temples in India. And again when they looted all of these places of their gold and silver.
Now they have done all that damage to the other treasures, it is safe to assume the adherents of the Religion of Peace would never, ever do another foolish act of violence to another priceless work of art.
And I freely admit it is ludicrous for me to assume otherwise. Don't know what came over me when I made the original comment. Sorry.
