Of course not. Do you have any idea how much work would be involved? Does anybody? Actual humans would have to examine zigabytes of data and make nuanced decisions that will make everybody’s lawyers happy.
The only conceivable solution is common-carrier status, which requires a certain amount of government oversight; even then, it will oblige Facebook to deliver every message, including the fascist ones. It would turn Facebook into a public utility. The phone company doesn’t get sued if I say horrible things on the phone, does it?
Trouble is, Facebook wants it both ways: freedom from responsibility for censoring your messages, and freedom to earn unlimited profits.
