Violence
Depictions of violence have been used as a pretext for banning books by school boards wary of disturbing content, and by authoritarian governments seeking to suppress accounts of their own atrocities. The same passage that gets a young adult novel challenged at a Texas school board might, in a different context, be the reason a dissident writer's memoir is confiscated at an airport.
