Extremist perspectives win sympathy and recruits because they offer narratives that claim to identify deep injustices and enemies.

The strength of democratic societies relies on their capacity to know how to stand firm against extremism while respecting justice in the means used to fight terrorism.

The biggest danger of this terrorism and extremism is the tarnishing of the reputation of our beloved religion... We will not allow this to happen.

Corruption is rife in the Muslim world, and when it is coupled with the marginalization of religion, it manifests itself as frustration and becomes a fertile recruiting ground for extremism.

Needless to say, oftentimes a 'religion' is not needed to breed extremism. People breed it all by themselves, oftentimes with the subjective morality of modern secularism breeding the worst kind.

We have to understand how the extremists got the way they are. Without that kind of understanding, we'd never really get to know them. I put in nothing about their childhoods. But what I have put in is stuff about the weird symbiotic relationship between us and them.

I would remind you that extremism in the defense of liberty is no vice! And let me remind you also that moderation in the pursuit of justice is no virtue.

Right-wing extremism is all about patience. That is, until it makes its move, and then it is sudden and explosive.

But 85 percent of the mosques have extremist leadership in this country. Most Muslims, the overwhelming majority of Muslims, are loyal Americans.

An intelligence analyst may attribute an attack to al Qaeda, whereas a policy maker could opt for the more general 'extremist.'

History proves that those who seed extremist ideologies reap a bitter harvest.

My lesson from history is that if there is a strong moderate centrist party which can lead the country, there is no room for extremists from the right or left.

Extremism in defense of liberty is not a vice, but I denounce political extremism, of the left or the right, based on duplicity, falsehood, fear, violence and threats when they endanger liberty.

Faith minus vulnerability and mystery equals extremism. If you've got all the answers, then don't call what you do 'faith.'

At the turn of the last century, extremists were forced back to the political fringes while younger politicians resurrected the vitality of the original Republican vision. They recognized that the nation could only develop and grow by protecting equality of opportunity for hardworking Americans at the bottom of the economic ladder.

It's absolutely shameful that Rep. Grijalva would try to use tribes as political pawns to implement the misguided agenda of extremist environmental groups.

Liberals in Congress have spent the past three decades pandering to environmental extremists. The policies they have put in place are in large part responsible for the energy crunch we are seeing today. We have not built a refinery in this country for 30 years.

I want education for the sons and the daughters of all the extremists, especially the Taliban.

Look I eat really well and I work out, but I also indulge when I want to. I don't starve myself in an extremist way. You're not taking away my coffee or my dairy or my glass of wine because I'd be devastated.

Ultimately, the forces of dictatorship and extremism robbed me of my mother, but she lives on as a symbol of hope, a role model for women across the world. She proved beyond a doubt, with her life and relentless courage, that women can certainly do everything.

Educated women armed with computers have defeated extremists by denying them a monopoly to define cultural identity and interpret religious texts. No extremist can say that women are inferior to men without being made a laughingstock on Al Jazeera. Islam insisted on equality between everyone.

Extremists think 'communication' means agreeing with them.

If you create something, you don't want someone else to go and profit from it; you have your right to make a living and everything. So I respect copyright. What I don't respect is copyright extremism. And I what I don't respect is a business model that encourages piracy.

Some feminists have this party-line attitude, and they can be very extremist. The most enlightened characters in my film are women.
