Mostly only illegal content should be removed.
And that's how you end up with a Nazi bar. Sure a swastica tattoo isn't illegal; nor is saying death to jews. But most people don't want to drink in that environment so if you don't kick (censor) the nazi's out then your business will not get non-nazi patronage (and maybe go under). The "free market" has determined that censorship is desired.
Did you read the article? Removing illegal content (like how to make a bomb) is a censorship, because sender and receiver are happy with it. We need to bring arguments like "the good of a society" to justify removing illegal content.
But harassment, threats and suchlike no one wants to get. Sender may be happy to send it, while receiver is not happy to receive. We need not to resort to a good for a society explaining, why these should be banned.
Idk where u from, but here in Russia it's not only socially unacceptable but is also a literal crime which falls under incitement of violence and rehabilitation of Nazi ideology.
In the digital space, filters work just fine. Your messages will live in the same database as the Nazi's, but you can be completely isolated from seeing them if you set up your filters accordingly.
These groups really like to spread lies about people and events. They love to manipulate third parties or institutions into attacking you too.
How many people like getting criticism of any form? Should we ban all criticism?
Evil is more nuanced and resourceful than that.
Russians looking top-down on Caucasians (from Caucasus, not in the American sense of the word) or Central Asians is a thing, but there are nuances, e.g. the relationship with Chechens.
Like very seriously, I am not saying Russia has Aryan supremacists. But it has strong enough and big enough groups that are so similar in everything except who gets to be on top, that "white supremacy" is perfectly good descriptor in English speaking forum. And neonazi fits perfectly their group behavior. Down to similar symbolism and preferred music.
Like take a protest (for whatever issue you want). Is that criticism or harrasment? Or both?
