That doesn't work.
If you really think you can "convince" people to tolerate others, feel free to go to Stormfront and convince the white-nationalists to stop being racist.
Go and try it. Its not like these hateful locations are unknown, its a free and open internet. Go an talk with them for a week. You might learn how easy it is to rationalize bigotry and racism.
At some point, you gotta just shut it down, like what the world did to 8chan. And these situations aren't hypothetical at all. You literally can go test your theory at Stormfront.
> Only when that evil speech turns into action does the society step in.
We're too late for that. Christchurch shooter, and then El Paso shooter. We've got a strain of intolerant speech that are inspiring lone-wolves to go into literal suicide missions to shoot people they don't like right now.
Gun control debate is locked. Its been like 2 weeks and everyone's already forgotten about the El Paso shooter. Nothing will come about with that.
But at least we shut down 8chan, one of the hangout spots for this hateful branch of people. We should probably shutdown other hangout spots too, like Stormfront.
