ISIS destruction of ancient art

By now, nearly everyone on the planet has been horrified by practically everything that The Islamic State, also known as the Islamic State of Iraq and al-Sham (ISIS) barbarians have done in the name of their medieval interpretation of Islam. 

Now the ISIS militants have destroyed ancient Assyrian sculptures at the Nineveh Museum in Mosul, Iraq, and posted videos of the destruction online, another level of barbarism has risen to the surface for these troglodytes. ISIS seized Mosul, Iraq, last June, and already rules an area larger than the United Kingdom. In this century, we've seen this unforgivable destruction of ancient art before in the region... remember when the Taliban destroyed the Buddhas of Bamiyan in 2001?

In their conquering process, ISIS has beheaded, crucified, burned, raped, enslaved and tortured an unknown but large number of their fellow Moslems, Christians and other assorted so-called apostates who do not subscribe to ISIS' strict interpretation of Islam.

I expect that the destruction of these antiquities will continue, forever destroying an important part of mankind's cultural heritage. What bugs me the most, is that (as far as I know) other than Sheik Abdullah bin Bayyah, and some clerics in Saudi Arabia, no other prominent Muslim cleric has issued a fatwa against ISIS.

Where are the fatwas, from clerics all over the planet, denouncing these mutants and their barbarism?

Personally, I think that we are being all somewhat misled, by perhaps a well-intentioned, PC-driven, incredulous, but intellectually dishonest Western worldwide effort to deny the Islamic State’s medieval mindset religious nature.

The reality is that the Islamic State is Islamic. Very Islamic. Yes, it has attracted psychopaths and adventure seekers, drawn largely from the disaffected populations of the Middle East and Europe. But the religion preached by its most ardent followers derives from coherent and even learned interpretations of Islam.

Virtually every major decision and law promulgated by the Islamic State adheres to what it calls, in its press and pronouncements, and on its billboards, license plates, stationery, and coins, “the Prophetic methodology,” which means following the prophecy and example of Muhammad, in punctilious detail. Muslims can reject the Islamic State; nearly all do. But pretending that it isn’t actually a religious, millenarian group, with theology that must be understood to be combatted, has already led the United States to underestimate it and back foolish schemes to counter it. We’ll need to get acquainted with the Islamic State’s intellectual genealogy if we are to react in a way that will not strengthen it, but instead help it self-immolate in its own excessive zeal.

This cancer within Islam must be destroyed and cured by Islam, and so I ask again:  Where are the fatwas, from clerics all over the planet, denouncing these mutants and their barbarism?
