Just like beauty, rudeness is confusingly both in the eye of the beholder and a universal phenomenon, something we’re supposed to recognize in an instant. At The New York Times Magazine, Rachel Cusk explores the complicated question of politeness from various angles — from Brexit and the Trump presidency to airport security checks and in-store shopping etiquette. But she also dives deep into the fundamental difficulty of separating honesty from being plain rude.

Are people rude because they are unhappy? Is rudeness like nakedness, a state deserving the tact and mercy of the clothed? If we are polite to rude people, perhaps we give them back their dignity; yet the obsessiveness of the rude presents certain challenges to the proponents of civilized behavior. It is an act of disinhibition: Like a narcotic, it offers a sensation of glorious release from jailers no one else can see.

In the recollection of events, rudeness often has a role to play in the moral construction of a drama: It is the outward sign of an inward or unseen calamity. Rudeness itself is not the calamity. It is the harbinger, not the manifestation, of evil. In the Bible, Satan is not rude — he is usually rather charming — but the people who act in his service are. Jesus, on the other hand, often comes across as somewhat terse. Indeed, many of the people he encounters find him direct to the point of rudeness. The test, it is clear, is to tell rudeness from truth, and in the Bible that test is often failed. An unambiguous event — violence — is therefore required. The episode of the crucifixion is an orgy of rudeness whose villains are impossible to miss. The uncouth conduct of the Roman soldiers at the foot of the cross, for instance, can be seen in no other light: Anyone thinking that Jesus could have done a bit more to avoid his fate is offered this lasting example of humanity’s incurable awfulness. They know not what they do, was Jesus’ comment on his tormentors. Forgive them.
