Now that I read myself again, the first quote you made of me does sound insulting. But you're making a false association based on that. People can think about something for decades, and still be filled with superstitions till their last breath.
On their death beds, people with religious beliefs are 4 times more prone to delirium than non-believers. And I believe it's cause they tried to conquer their fear of death by taking a bad tool like religion. When there are tools out there harder to master, but giving much better results. Like philosophy. Or just "Not giving a fuck about dying". That's working great for me.
Also, someone can think about something for 2 seconds, and happen to be right on the first guess. And someone can be wrong about something, and just add meat over and over around their false beliefs. Time tend to make us wiser, but it's not a one-way ticket.
I'm thinking a lot about your second point (If you were a king), which sounds simple, but open up a lot of doors. I think deep down inside of me, there's fear of the unknown. Could you describe what you think the overall effects on society would be if there really was pure freedom of speech in your kingdom?
It's funny cause I'm watching an old show right now called Fantasy Island. Where a distinguished French host receive people on his island, promising to make their best fantasy come true. There's 2 different fantasies per episode, and there's 7 seasons total. Some episodes are on Youtube if you want to see what I'm talking about.
I think your fantasy of a society with absolute free speech would make a very good episode. And most of the times, there's gonna be a "Be careful what you wish for" kind of twist in the scenario. People will realize that there's always downsides to their fantasies. When at first, they only see the good sides, and they expect to spent a perfect week-end filled with pure joy. But it's never happening.
Your last point (about not allowing violence in response to free speech) have me wonder about your definition of violence. Are you considering psychological violence? Cause most people, when they know they can't hurt someone physically, will find twisted ways to make people's lives miserable. The "Informal social control" effect I referred to earlier, works in insidious ways.
Also, not only physical violence is likely not to be reported to justice, but psychological violence is almost never reported. So I don't think freedom of speech would be much greater than it is today. And it would save the US government billions that they would not waste anymore on censorship, so they will just finance more wars. Be careful what you wish for! Haha. Don't worry, I'm kidding.
But what would be a good effect of absolute free speech would be that rich and/or powerful people would not be allowed to fire artists or comedians who supported something they didn't like. Let's take the case of Louis CK. Normally, this exceptional comedian would already be back on TV by now, but people are scared as shit in USA. They fear they could also drown in quicksands if they just say something like "I think the guy is a good comedian, and I would love to see him back on TV.". It could be enough to end their career. And this is also part of the "informal social control" effect, even if it's made by rich people. Cause it's not about the law, it's about personal vendettas.
That's a really sad thing about censorship. Cause a few people can decide to deprive 100 millions people of a comedian they love, someone who make their lives better, make them better persons. And the reason why they do that, is cause 3 grown up women's saw his penis. Nonsense. Absolute nonsense. We see breasts all the times, almost everyday, and nobody call themselves victims. But apparently, seeing a penis is an horrible experience. Worst than death.
So I still don't think that free speech should be absolute, but I would not mind to live in your kingdom for 1 or 2 months, just to see what happens. It would certainly be a valuable experience.
