Although uke2se is obviously doing a Poe, you seem to actually believe what you are posting. Are you really running with the idea that if we sanitize free speech enough, nobody will do wrong?
Have you considered the possibility that while some might be influenced to do wrong when reading the "wrong" opinions, others who might have done wrong could be influenced to change their mind about doing wrong because of exposure to counter opinions?
Yes. I have myself changed opinions radically on receiving new information.
I have also gone down the rabbit hole on several occasions. Notably, becoming a borderline Truther and
really went down the rabbit hole on Peak Oil. It's been more than ten years, but I remember being convinced that modern society was about to go off a cliff with famine, population contraction and resource wars, as not a fun time. I have some empathy for people who fall into cults or wholeheartedly believe narratives.
And you are right, I got out of those things because I seek out information and test my convictions.
These information rabbit-holes exist by omitting counter-arguments and blatant dishonest arguing.
Simply presenting argument and counter-argument is not enough (Today on Geraldo; The Holocaust, did it happen or not? Find out after the break!).
The matter is often framed as:
The argument for censorship: These are private companies, they can choose what they let on their platforms
The argument against censorship: These platforms are so big that they are now where public discourse takes place, and should thus be seen as public utilities and we can invoke the US constitutional right to free speech.
But the more I think about this, and place myself in the shoes of the platforms; Can we even reasonably ask for-profit companies to broadcast certain forms of speech? Can we really demand a corporation make itself complicit in a possible mass shooting or lynching?
Hence my billboard example.
Alex Jones is a good example. Can you have some dude constantly blast professionally produced blood-libel against "the elite" into the public consciousness and then, when one of his fans shoots Gabrielle Gifford, throw up your hands and claim innocence?
Unless we make laws that force platforms to spread (possible) hate-speech, thereby making them immune to legal repercussions, it is inevitable that the platforms will try to protect themselves and will ban certain speech.
