I love Ann Coulter, but it's not realistic to think you can go in and convert all these folks to Christianity at the point of a gun.
A more likely technique is divide and conquer. The better-educated Muslims may want to consider themselves too enlightened to resort to violence. The minority Shiite Muslims don't get on very well with the Sunni Muslims. Muslims in Indonesia are said to practice a somewhat different religion from their brothers in the Mideast.
Apart from fighting a war on several fronts against the violent Muslims, we need to mount a huge propaganda effort to convince the others that the true version of Islam is peaceful, and doesn't go around murdering innocent people. I don't know if that's true or not (given that Mohammed himself wielded a sword). But for every Muslim cleric who proclaims the Jihad, we have to get some other cleric to preach the opposite way. Otherwise, we're all in big trouble, fighting against nearly a third of the inhabitants of earth.
Even if we win, it would be no fun wiping out hundreds of millions of people to do it.
Of course Ann Coulter never said that.
She said kill their leaders, you know the ones who are teaching them that cold-blooded murder is okay in the name of Allah.
You either did not read what she said, or you simply decided to make up what you wanted and then attribute that to her.
Her point was that the root cause of this entire Jihad attitude is the religion they are forced to stick with, Islam.
You may disgree with converting them to Christianity, but you cannot say she said to convert anyone to Christianity at the point of a gun, she never did.
Now that is entirely their choice, isn't it.
Seems to me that they all have the option of eradicating the terrorists among them and not just pay lip service to "disapproving" of terrorism.
