You can get so close to that line without crossing it though, plus policing 300 million users is hard enough. The problem is that both extreme fascism and communism might actually be a very tempting response to everyday problems to a lot of people, which means that the only reason we haven't had issues with either ideology is we had a media who complied with the censorship of both those viewpoints. Online anyone can say anything and promote anything, which means people who have problems that aren't being solved by their current leaders can easily turn to ideologies which we had all previously agreed to censor out of normal discourse.
