Facebook CEO Mark Zuckerberg has come under fire after refusing to remove Facebook pages like the Infowars from the social networking website lest it curb freedom of speech.

The big picture: In an interview published by Recode, Zuckerberg said that while he found Holocaust denial to be deeply offensive, “at the end of the day, I don’t believe that our platform should take that down because I think there are things that different people get wrong. I don’t think that they’re intentionally getting it wrong.”

Zuckerberg went on to say that Facebook will remove content “if it’s going to result in real harm, real physical harm, or if you’re attacking individuals.” Otherwise, he said, “you can put up that content on your page, even if people might disagree with it or find it offensive.”

Zuckerberg’s statement attracted controversy reigniting a debate over where tech companies should draw the line when it comes to free speech.

The update: Kara Swisher has updated on Recode that Zuckerberg has clarified his remarks through an e-mail sent to her. “I personally find Holocaust denial deeply offensive, and I absolutely didn’t intend to defend the intent of people who deny that,” he wrote.
