How would that work in practice? Say I run a forum and I want to take down a post that's calling for a mosque to be blown up. Should I need to hire a detective to discover the identity behind the account, file a lawsuit, serve that person some papers, and wait for the case to make its way through the courts? Do I need to leave the post up while that's taking place?
Typically in such cases posts are placed in limbo - still present but usually inaccessible while legal questions are answered.
Courts should be making these decisions, not companies interfering in other companies.
Why?
Because at the end of the day these are questions "the people" need to answer, not unelected managers at tech companies.
A few people do not have the right to silence the voice of millions. That's what's happening, fundamentally, and it is being cheered, and you all somehow think this is going to end well.
