Used by Paul Craig Roberts:
"Insouciant gullible Americans are expert at fleeing from unsettling bad news. Thus, they pave their own path to tyranny. Tyranny is easy to establish over peoples who have confidence in their Constitutional rights and integrity of their institutions. The more patriotic the population is, the more susceptible it is to deception and betrayal by government. Try telling patriots what is happening to them, and they will call you a commie for speaking badly about their beloved country.

"Christian evangelicals have no opposition to the evil that is engulfing us, because they have been brainwashed that they will escape it by being wafted up to Heaven. The growth of evil is actually their escape from a sinful world into Heaven. The more evil, the sooner their escape."
