In a wide-ranging interview with Recode published Wednesday, Facebook CEO Mark Zuckerberg suggested that Holocaust deniers may not know they're spreading a lie. Zuckerberg recently came under fire for letting blatantly false posts, such as those claiming the Sandy Hook shooting didn't happened, remain on the site. "I don't think that they're intentionally getting it wrong," Zuckerberg said of Holocaust deniers, claiming that "everyone gets things wrong" and that it's hard to determine whether they intended to do so. That's why posts determined false by fact-checkers are moved down in users' timelines, but not necessarily stripped from Facebook entirely, Zuckerberg explained. Hours later, Zuckerberg tried to clarify his remarks, saying he finds Holocaust denial "deeply offensive" and believes that "removing the distribution of misinformation — rather than removing it outright — strikes the right balance between free expression and a safe and authentic community."
