Mark Zuckerberg seems to think Holocaust deniers don't realize they're lying when they spread that hoax on Facebook.

In a wide-ranging interview with Recode founder Kara Swisher published Wednesday, Zuckerberg was questioned about why Facebook doesn't remove objectively false information, like claims that the Holocaust or the Sandy Hook shooting didn't happen. His response? "I don't think that they're intentionally getting it wrong."

Facebook recently came under fire for allowing InfoWars, a consistent spreader of false information and hoaxes, to stay on the site. Swisher asked Zuckerberg why such conspiracy-peddling sources are granted a presence on Facebook. Zuckerberg responded that while Holocaust denial is "abhorrent" and "deeply offensive," it can be hard to "understand the intent" of those who post false statements such as Holocaust denials.

"Everyone gets things wrong, and if we were taking down people's accounts when they got a few things wrong, then that would be a hard world for giving people a voice and saying that you care about that," Zuckerberg said. So when Facebook's fact checkers identify a hoax, the site simply moves them down in users' News Feeds instead of removing them altogether.

Something that would be removed? "Going to someone who is a victim of Sandy Hook and telling them, 'Hey, no, you're a liar' — that is harassment," Zuckerberg explained. Read or listen to the whole interview at Recode. Kathryn Krawczyk
