Political correctness is frustrating enough already, but Dalrymple notes that it’s even more so when you are unable to dissent or are condemned for doing so:
The problem with the posters in the airport was that they resembled the political propaganda of a totalitarian regime, insinuating what could not be dissented from without some danger or personal inconvenience. I do not mean to say that we now live in such a regime in the most literal sense, that we have already to fear the midnight knock on the door, but rather that the posters contribute to a miasma of untruth, the kind of untruth that is becoming socially dangerous, or at least embarrassing, to point out. For if you do dissent from such a slogan you will be immediately cast into the social Gehenna where the reactionaries are sent, whose cries of outrage can be dismissed merely by virtue of who they are.
