I think he's confusing cause and effect. The terrorists' war on us is the result of Christianophobia, and Judeaphobia, and all-other-religions-including-moderate-Islamophobia.
Its not as if someone "suddenly" hijacked their religion. Look at the campaign to conquor Europe hundreds of years ago. They established Spain as a Western capital of Islam.
To further the "political" side of Islam, the "Ask The Imam" sites say that while slavery is permissible for those captured in jihad, they must be brought to an Islamic territory to be divided up. Christianity knows no boundaries but obviously Islam does declare them.
That their legal system differentiates between muslims and those of other all religions puts them on par with Germany's Nazis (yet even more extreme).
Other nations used to follow this model. It is why the colonists came to America, to escape religious persecution.
Some Islamic nations (like Saudi Arabia) don't even permit the open practice of other faiths. Forget about "tax exempt status" or "official recognition" of a religion, active suppression of other faiths. Yet muslims know all about how "evil" it is to suppress a religion; they all agree that the undeniable trigger for physicial holy war (jihad) is to outlaw/restrict the practice of Islam.
