My point isn't about radical Islam (no quotes needed, it does exist), but rather about privileged Western know-it-alls who feel the need to lecture about things with which they have no experience. Especially to people who have experienced these things firsthand. Radical Islam is but one example. American Communists lecturing Eastern Europeans is another.
