Twitter, or any social media platform, has certain guidelines and standards they enforece. They may be inefficiently, inconsistently, or even poorly enforced, but they exist. As soon as Twitter, Facebook, Google Plus (snort), QQ, or any social media platform du jour decides to enforce action against any group, they have made a choice. If someone sends death threats, harasses some celebrity, attacks some sponsor, or repeatedly goes after some head of state with violent, or even merely crude, comments and the platform takes action against said person they can no longer claim they don’t support or allow some idea by not taking action.
If you want to not moderate such things, then you get every platform becomes 4chan. Nothing is prohibited. But if you decide to enforce any action for any reason, then you decline to go after Nazis for inciting hatred, violence, and generally being the shittiest people on earth? Then you have decided to side with Nazis, full stop.
There is either no line, or the line is drawn somewhere. Nobody is calling for banishing American Conservative, the Federalist, National Review, Fox News, or even Breitbart to the dark web for political beliefs. This isn’t trying to banish right wing political thought. That would be bad. Instead we are talking actual fucking Nazis, whose platform advocates literal genocide, criminalizing people for their race, and generally being people the world would be better off without. If you draw the line where a registrar choosing not to do business with groups whose sole purpose is pushing Nazi ideology, when they can, and will, choose not to do business for a whole host of other reasons, you are indeed saying they should support those Nazis.
And if you decide that, what of those who are in the crosshairs of such hate groups? Do you not think that, because of their race, that their rights might not be infringed by allowing Nazis unfettered access to public spaces?
And how would you propose countering Nazis? If shouting them out of the public sphere (hey, they were there for a long time until public pressure got them forced out) isn’t ok, and punching them isn’t ok, then what? Simply politely ask them to stop being racist would be genociders? How well did that work in the 30’s.
And if the answer to bad speech is more speech, and people voicing their opinions and voting with their wallets (after all, why did the registrars drop Stormfront now? Hint: it has to do with people saying they would not use their business if they associated with Stormfront) is the public using speech to counter Nazis, then this is a good solution, no? Boston basically cowing their little crying Nazi party by showing up en masse was pretty damn encouraging. People pressuring companies to enforce their rules and pushing Nazis out of the public sphere is equally so.
In short if the question is do we push them out of the public, or sit by politely while they spread hate as you suggest? I’m gonna say FUCK THAT.
