None of the three has any basis for such assertions. To state the obvious: as non-Muslims and politicians, rather than Muslims and scholars, they are in no position to declare what is Islamic and what is not. As Bernard Lewis, a leading American authority of Islam, notes: “it is surely presumptuous for those who are not Muslims to say what is orthodox and what is heretical in Islam.” (That Obama was born and raised a Muslim has no relevance here, for he left the faith and cannot pronounce on it.)
Indeed, Obama compounds his predecessors’ errors and goes further: Clinton and Bush merely described certain actions (treatment of women and children, acts of violence against innocents) as un-Islamic, but Obama has dared to declare an entire organization (and quasi-state) to be “not Islamic.”
The only good thing about this idiocy? At least it’s better than the formulation by the Council on American-Islamic Relations (known as CAIR) which has the nerve to call ISIS “anti-Islamic.”
In the end, though, neither U.S. presidents nor Islamist apologists fool people. Anyone with eyes and ears realizes that ISIS, like the Taliban and Al-Qaeda before it, is 100 percent Islamic. And most Westerners, as indicated by detailed polling in Europe, do have eyes and ears. Over time, they are increasingly relying on common sense to conclude that ISIS is indeed profoundly Islamic.
