These are the stories our readers cared about most this year:

1. Social media censorship and nudity bans

In response to complaints from artists about Instagram’s restrictions on photographic nudity, NCAC launched its #WeTheNipple campaign that included an art action at Facebook’s New York headquarters. Images of the art action were swiftly removed from Instagram, though Facebook later agreed to reconsider its artistic nudity policies. NCAC met with Instagram policy team members, artists and curators to discuss ways forward. We’re working with artists and other groups negatively affected by social media censorship and will continue to advocate for improvements in content moderation, including robust, transparent notifications and appeals processes for both content removal and the range of actions often referred to as “shadowbanning.”

2. Increased challenges to LGBTQ content

Three quarters of this year’s top ban and challenged books were titles telling LGBTQ stories. Over the year, we saw complaints about teaching LGBTQ history books, removals of books from librarieschallenges to entire reading initiatives and cancellations of events featuring LGBTQ writers and performers.

3. San Francisco school mural controversy

George Washington High School announced plans to remove murals commissioned by the Works Progress Administration due to concerns about depictions of people of color. Artists, activists and community members demanded the murals be preserved. NCAC urged the school to reconsider and to hold a public forum about the murals that included student voices.

The board ultimately reversed the decision to destroy the murals, but the debate about what to do with them continues with passionate advocates on all sides.

4. Reading restrictions in prisons

Federal courts have repeatedly affirmed that prisoners have a First Amendment right to read, and publishers and others have a right to send them reading materials. While those rights can be restricted in the interest of security, blocking the free flow of ideas serves no penological purpose. Regardless, we’ve seen bans on prison newspapers and dozens of books from prisons across the country.

5. Universities stifle art and drama to avoid controversy

From library art displays to student artwork featuring nudity, universities have been quick to remove work from campus display. Several student theater productions have been cancelled over race-related complaints, including, notably, a production of Larry Shue’s The Foreigner, which depicts the KKK as a caricatured villain, and an updated version of Elmer Rice’s The Adding Machine, a play about hatred and intolerance in America.

NCAC is working with the Dramatists Guild to combat this rise in theater censorship on college campuses.

6. Museums appear increasingly fearful of tackling controversial issues and alienating audiences in a polarized time

New York’s El Museo del Barrio cancelled a retrospective of the work of Chilean filmmaker Alejandro Jodorowsky. This cancellation is just one example of art institutions cancelling or modifying shows in response to public pressure.
