No. Absolute free speech means allowing people say whatever they like and that means anything. You can spam somebody with messages telling them to kill themselves. You can put a loudspeaker in front of somebody’s house and play a message on loop telling them to kill themselves. You can openly call for somebody to kill another person and not get in trouble for enticing a murder. You can shout down anybody you like and tell them to shut up or threaten them, all you have to do is be louder and look like you have the means to kill them in order to intimidate. And that will all be fine because if someone tries to stop you from expressing your opinion, they will be infringing on your right to absolute free speech.

It does however create a paradox: if someone uses their free speech to infringe on somebody else’s free speech, what can be done? You can’t tell the person infringing to stop because that would infringe on their free speech. After all, they have a right to absolute free speech, don’t they? So, if you say “your right to free speech ends where the right of somebody else’s begins” then it’s not absolute anymore.

It also opens a can of worms as to what counts as expressing free speech and what counts as suppressing it. Does blocking somebody on a platform infringe on their right? Does muting? If the rule is “right to speak, but no right to be heard”, what counts as speech? Does typing and hitting send count as free speech? Well, I could give you an app with a textbox and a send button, disconnect you from the internet, and you could write everything you want, hit send and it never leaves your computer but you did express yourself, didn’t you? Or maybe the sounds coming out of your mouth count as speech / expression ? Well, I could gag you, you can make sounds and that’s speech, right?

So no. I don’t believe absolute free speech can exist.
