Just a curious question: is Apple applying the same standard and blocking also black supremacist and black nationalist (and say Islamacist stuff that is clearly anti-others) with the same vigour as it blocks white supremacists and neo-Nazis?

A double standard in this matter would send a terrible message.

Is anybody else worried that this "Shut off from the world" approach might not solve the problem at its root?

I'd worry that it wouldn't resolve the underlying tension but would only up the anger and cause them to retaliate in the only form they can - violence.

... you say that like this wasn't literally a response to their present violence.

So this is how we prevent wars in the 21st century. Insurgent DoS.
