It's not like people are approaching Facebook and asking "Please may I make a post to organize a murder". Facebook doesn't learn about the content of the posts until after the fact, so the analogy with the knife seller is not really valid. > We can actually make this analogy a little clearer: would you sell a knife to someone knowing they planned to stab you Absolutely. This would be an excellent opportunity to sell them a fake knife. Also, now I'm aware that someone is trying to kill me, so I can do something about it. Kind of a best case scenario for me. > They should prevent behavior they disagree with Voting for a particular candidate would be an example of behavior that Facebook might try to prevent. I find it highly disturbing that anyone would want to assign Facebook the power of controlling our behavior. That is a power we grant to governments, and then reluctantly, and only with appropriate checks and balances. Not something we should hand out to private companies with no accountability.
