>But you want Reddit to literally adopt 8chan's moderation policy, I want reddit to adopt the public square's policy of allowing any content that isn't illegal, which also happens to be pretty much synonymous with 8chan's policy. Do you consider the town square (which has the policy of allowing content that is not illegal) a center of inspiration for mass shootings? Could it be that the public square is not viewed as…
"Do you consider the town square a centre of inspiration for mass shootings" Before the internet, yes, definitely. Maybe not mass shootings specifically because that seems to be a recent fashion trend after Columbine, but violent extremism in general. How do you think Hitler managed to secure over 40 percent of the democratic vote in the early 1930s? How did Osama Bin Laden recruit extremists who were willing to put…
I believe quite the opposite. It has been a place for the public to plan self defense, both to organize themselves in defense from natural disaster, hostile forces, wildfires, and anyone who seeks to do them harm. It is a place for the public to engage in the marketplace of ideas and inspirations, which ultimately leads to the saving of lives, prosperity, security, and bonding of the populace. Harmful ideas can be shamed and those espousing bad ideas have a chance of learning the holes in their ideas. The mass shooter espousing violent ideas in the public square is as likely to have alerted his neighbor to be alert for any evidence of crime, as he is to convince the general populace of his nutjob ideas.
I don't buy your hypothesis that Hitler came to power because of free speech, and quite frankly it is laughable to think banning Hitler from Reddit (were it to exist in his day) would have any effect whatsoever. You seem quite ignorant of the factors precipitating Naziism, including the economic situation of Germany at that time. It's also worth noting that Hitler was quick to stifle certain speech that went against his ideas, meaning he found free speech at odds or even dangerous to Naziism.

>How did Osama Bin Laden recruit extremists who were willing to put a bomb into the WTC basement? Propaganda, speech.
Bin Laden attempted to blow up the WTC basement with bombs, not free speech. Bin Laden lived in Muslim nations with more limited speech regulations than Reddit.
>Moreover you have to recognize that these isolated echo chambers would naturally self-segregate on Reddit if given free reign, and so in practice you haven't changed anything aside from giving these ideas more distribution. It's not like /r/88 or whatever would be interacting with the rest of Reddit thus helping their members deradicalize.
Some may, some may not. I've stopped using reddit because I was banned because I simply said things like I didn't believe forcefully shutting down a restaurant is an appropriate way to deal with coronavirus. Now maybe that is a very wrong and bad idea, but I'm willing to debate with others on it and learn their perspectives. Instead these communities said fuck you, you're banned, and now you have to go to some echo-chamber where everyone agrees with it. I'm not interested in an echo chamber, I'm interested in engaging with others so my bad ideas can be brought to light and shown to be bad, or my good ideas can be integrated. Your argument sounds more like one against having subreddits.
