Real citation: "Islamists like to use a similar tool of control to stifle freedom — free speech, criticism of their beliefs or their politics, artistic expression — in countries that, remarkably, aren't Islamist theocracies and in which they're even minorities in the population. Ever since 9/11, the new normal has been that anything could drive a Muslim into a homicidal rage at any moment, and you don't have any clue what it is, so it's better not to take chances. Okay, so that may be a stereotype that the vast majority of non-batshit-bombthrowing-crazy Muslims resent, but it's certainly proven useful to the real agitators among them."

Made-up citation: "I don't expect my children to be perfect little angels. As long as the report cards keep saying 'non-batshit-bombthrowing-crazy' and they don't get mud on the carpet, I'll be a proud papa."
