Say it were implemented in this world and you could say anything you like (written, spoken, signed whatever) to anyone who can hear/read/see it. What kind of problems could that create and are there any ways to resolve them without limiting that absolute free speech?
Could it even create unsolvable logical errors? E.g an omnipotent god can’t create a stone too heavy for itself to lift. Maybe there are similar things with absolute free speech.
Free speech and freedom of opinion, in my understanding, are two very different things.
The “free speech” touted by the usual actors is the thing that, if truly implemented, would get most people punched in the mouth. People tend to confuse the possibility of saying anything they want and not being censored for their words/ideas with the notion of speaking without concern and not receiving any sort of consequences.
So, to the extent of my comprehension, free speech would lead to violence.
Freedom of opinion, again, as I understand it, is the recognized right to differ from the socially recognized and established view on any subject but understanding that, regardless your freedom to diverge from it, you are responsible for your words.
