Facebook: Free Speech Is Really Hard

In the wake of the controversy surrounding the Holocaust denial groups on Facebook, Randi Zuckerberg, the site's marketing director (and sister of founder Mark), said Tuesday that it's difficult to navigate the ins and outs of the First Amendment.

"Free speech is really hard," Zuckerberg said at the Personal Democracy Forum in Manhattan. "It's something that we believe in very passionately as a company but it's a really hard issue."

Facebook took some heat last month after it refused to pull down Holocaust denial groups. The site eventually removed two groups after members made violent statements, but Facebook said its terms of service allows members to speak their minds as long as they do not advocate violence against other people.

"Our terms of service claim that if you are saying something that is hateful [or] if you are spreading words of violence that it comes down immediately," Zuckerberg said.

"When you have a site with over 200 million people, [they] are going to say things that are controversial or you don't agree with or that personally may make you furious or upset," she continued. "But just because they say that doesn't mean that it's hate, it doesn't mean that we should be censoring it. So it's a very difficult line, and that's where we are right now."
