Still, the negative reaction to Zuckerberg's initial comments was swift.
The young leader also explained why his platform gave a certain amount of leniency even to views he finds deeply offensive such as those expressed by Holocaust deniers. But, he adds, "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".
"Sometimes countries may have laws on the books - this is certainly true in the United States, I can say as an American lawyer - that are really out of date with how that culture thinks about speech, that are no longer enforced".
Mr Zuckerberg said: "Let's take this closer to home. I don't think they're intentionally getting it wrong".
Facebook's tweets said: "We see Pages on both the left and the right pumping out what they consider opinion or analysis - but others call fake news".
In response to the criticism, he later said: 'I personally find Holocaust denial deeply offensive, and I absolutely didn't intend to defend the intent of people who deny that.

Swisher: In the case of the Holocaust deniers, they might be, but go ahead.
"What Mark Zuckerberg needs to understand the intent of Holocaust deniers is not the sole proper standard of judgment", Kapoor wrote on Twitter. "Facebook has a moral and ethical obligation not to allow its dissemination". On Tuesday, the company's global head of policy management, Monika Bickert, testified before the House Judiciary Committee, where representatives grilled her on why Facebook allows Infowars to maintain an official page on its network, particularly after an armed gunman burst into a D.C. pizza joint based on bogus child trafficking claims propagated in part by Jones's site.
Zuckerberg has repeatedly said Facebook avoids banning content because it is hard to differentiate between outright falsehoods and analysis or opinion.
"Reducing the distribution of misinformation - rather than removing it outright - strikes the right balance between free expression and a safe and authentic community", Facebook said in a statement Wednesday.
CNBC reports that under the new policy, text and image items created or shared with the objective of immediately "contributing to or exacerbating violence or physical harm" will be removed. It consulted with a local organization to confirm the misinformation could lead to violence, then removed the posts.
Because Facebook is used to communicate by billions of people around the world, the company assessed that its policies have a significant impact on the freedom of speech.
