From a 2007 Reason interview with Ali:

Reason: Should we acknowledge that organized religion has sometimes sparked precisely the kinds of emancipation movements that could lift Islam into modern times? Slavery in the United States ended in part because of opposition by prominent church members and the communities they galvanized. The Polish Catholic Church helped defeat the Jaruzelski puppet regime. Do you think Islam could bring about similar social and political changes?

Hirsi Ali: Only if Islam is defeated. Because right now, the political side of Islam, the power-hungry expansionist side of Islam, has become superior to the Sufis and the Ismailis and the peace-seeking Muslims.

Reason: Don’t you mean defeating radical Islam?

Hirsi Ali: No. Islam, period. Once it’s defeated, it can mutate into something peaceful. It’s very difficult to even talk about peace now. They’re not interested in peace.

Reason: We have to crush the world’s 1.5 billion Muslims under our boot? In concrete terms, what does that mean, “defeat Islam”?

Hirsi Ali: I think that we are at war with Islam. And there’s no middle ground in wars. Islam can be defeated in many ways. For starters, you stop the spread of the ideology itself; at present, there are native Westerners converting to Islam, and they’re the most fanatical sometimes. There is infiltration of Islam in the schools and universities of the West. You stop that. You stop the symbol burning and the effigy burning, and you look them in the eye and flex your muscles and you say, “This is a warning. We won’t accept this anymore.” There comes a moment when you crush your enemy.

Reason: Militarily?

Hirsi Ali: In all forms, and if you don’t do that, then you have to live with the consequence of being crushed. […]

I don’t understand how anyone could consider such an attitude consistent with Enlightenment values in the secular Western tradition in general or with our U.S. Constitution in particular.
