It’s easy to spot overt calls for censorship from the commentariat. Those have become more common in the wake of both tumultuous events (like the violence questionably attributed to the “Innocence of Muslims” video, or Pamela Geller’s “Draw Muhammad” contest) and mundane ones (like fraternity brothers recorded indulging in racist chants).

But it’s harder to detect the subtle pro-censorship assumptions and rhetorical devices that permeate media coverage of free speech controversies. In discussing our First Amendment rights, the media routinely begs the question — it adopts stock phrases and concepts that presume that censorship is desirable or constitutional, and then tries to pass the result off as neutral analysis. This promotes civic ignorance and empowers deliberate censors.

Fortunately, this ain’t rocket science. Americans can train themselves to detect and question the media’s pro-censorship tropes. I’ve collected some of the most pervasive and familiar ones. This post is designed as a resource, and I’ll add to it as people point out more examples and more tropes.
