I don't understand that statement. I believe North Korea is a totalitarian state with concentrated power in few hands and no tolerance for dissidence. Are you saying they allow non-state actors to speak and take action freely to promote extreme ideologies there?

North Korea became north korea because of censorship. It is the most censored country in the world. And the point is that there is not "extremism" in north korea because censorship allows only "authoritarianism". That's the world you want to live in?

I agree with you that censorship is extremism and it should be fought against.

Extremism to a Westerner perhaps. Certainly, the ideology behind North Korea would be censored in most of the proposals on this thread, but given that the government of north korea would not and it is the only government with any control over the country of North Korea, I don't understand by what metric you could possibly say it's extremism. Unless you're appealing to divine justice or something, which would be great, but I sincerely doubt it.
