There is an ongoing problem for those who run Facebook since several nations in the world define “defamation” as synonymous with writing the truth about dictatorial regimes. Turkey has numerous laws which make it a crime to say anything about the Armenian genocide, oops, I just broke the laws of Turkey by employing those two words-Armenians and genocide. China constantly demands removal of comments that represent the idea of free speech because in the land of China those in authority decide who can speak and what anyone can say. Thus the issue confronting Mark Zuckerberg is whether or not to accept these restrictions and allow Facebook to continue functioning around the world. Imagine if Nazi Germany was around and Hitler decided what could or could not be stated on Facebook?
I do not know the answer to this question. It must be extremely difficult for Zuckerberg to run an organization which daily confronts issues of free speech. I admire him for his efforts to continue Facebook as an an important institution while at the same time being controlled by petty dictators. This is one complex problem that is the complex problem for Mark, not Fred!
