An African-American artist, Parker Bright, has conducted peaceful protests in front of the painting since Friday, positioning himself, sometimes with a few other protesters, in front of the work to partly block its view. He has engaged museum visitors in discussions about the painting while wearing a T-shirt with the words “Black Death Spectacle” on the back. Another protester, Hannah Black, a British-born black artist and writer working in Berlin, has written a letter to the biennial’s curators, Mia Locks and Christopher Y. Lew, urging that the painting be not only removed from the show but also destroyed.
“The subject matter is not Schutz’s,” Ms. Black wrote in a Facebook message that has been signed by more than 30 other artists she identifies as nonwhite. “White free speech and white creative freedom have been founded on the constraint of others, and are not natural rights. The painting must go.” She added that “contemporary art is a fundamentally white supremacist institution despite all our nice friends.”

The protest has found traction on Twitter, where some commenters have called for destruction of the painting and others have focused on what they view as an ill-conceived attempt by Ms. Schutz to aestheticize an atrocity.
