When you live in a country which holds freedom of religion as one of its founding principles, what do you do about adherents to a religion whose founder exhorted the faithful to impose that religion on others at the point of a sword?
Or at the muzzle of a gun?
Or at the flashpoint of a weapon of mass destruction?
Answer: when their freedom of religion threatens your country's survival, you do what you have to do to make sure the country survives.
We're not there--yet. But some people want us there. And I believe that one of them sits in the Oval Office.
UPDATE: Major Nidal Malik Hasan, the Fort Hood Shooter, tried to contact al Qaeda months ago and the FBI knew about it. Hasan also attended the same mosque and at the same time as two of the 9/11 hijackers.
I suppose that it is mere coincidence that this mosque, Dar al Hijrah Islamic Center in Falls Church, VA, nurtured jihad so fervent in at least three of its congregants, that they felt compelled to produce such high body counts for Allah.
