This shit will only stop when enough of the jihad preaching imams get dragged into the street and beaten to death. They are cowards who send their weak minded slaves out to do their dirty work. When they discover that they themselves will have to pay the price for their hate preaching, it will stop.
Use the Vlad Tepes method to discourage the invaders.
The only thing Muslims have respected in the last 1400 years is superior and overwhelming force.
And that's where the responsibility of the ostensibly "moderate" Muslim world lies.
The West—Christianity—the rest of the civilized world—whatever you want to call it—shouldn't have to be the ones that solve this problem.
But it will be one of these two groups that imposes the remedy.
Therefore, it would be much better for the world, and for civilized Muslims, if the Muslim world destroyed this scourge for themselves. After all, it's their religion which has supposedly been hijacked!
It's a crisis of faith and culture for the entire Muslim world, and their very survival depends on it. They'd better wake up. Thus far, I see far too much timidity and denial in the so-called "moderate" Muslim community...
