Ayaan Hirsi Ali

"... As you read this, Ayaan Hirsi Ali sits in a safe house with armed men guarding her door. She is one of the most poised, intelligent and compassionate advocates of freedom of speech and conscience alive today, and for this she is despised in Muslim communities throughout the world. The details of her story have been widely reported, but bear repeating, as they illustrate how poorly equipped we are to deal with the threat of Muslim extremism in the West."
