See, this is the problem again. The form of socialist society that exists in Korea is one that was formed through direct practice and based on Korea's existing situation. It's what works for them, regardless of whether or not you approve of the "model." You're saying it isn't "promising," more gesturing to potentials of misconduct that you percieve based on your own comparison to the ideal, perfect, impossible version of socialism that exists purely in imagination.

The problem rests on your belief that you know better than the millions of people in the DPRK over the last century how to run their country, without doing the study to see how and why their structures were formed. For example, the Democratic Front is an integral part to their socialist democracy, and this has heritage in liberation from colonialism by Japan. The various councils and committees have heritage in the culture formed in Korea and were solidified into a state.

Then, you go and strawman people and misrepresent them. Though you maintain a polite tone, your actual actions speak against that, and thus you aren't acting in a comradely way like you first seemed to be. It's frustrating.

However, a committee-based democracy with a ban on antagonistic propaganda does not sound promising.

Comrade Bordiga limits himself to upholding a cautious position on all the questions raised by the Left. He doesn’t say: the International poses and resolves such and such a question in this way, but the Left will instead pose and resolve it this other way. He instead says: the way the International poses and resolves problems doesn’t convince me; I fear they might slip into opportunism; there are insufficient guarantees against this; etc. His position, then, is one of permanent suspicion and doubt. In this way the position of the “Left” is purely negative: they express reservations without specifying them in a concrete form, and above all without indicating in concrete form their own point of view and their solutions. They end up spreading doubt and distrust without offering anything constructive.

but I don’t know how to find neutral sources.

Unless you have investigated a problem, you will be deprived of the right to speak on it. Isn't that too harsh? Not in the least. When you have not probed into a problem, into the present facts and its past history, and know nothing of its essentials, whatever you say about it will undoubtedly be nonsense. Talking nonsense solves no problems, as everyone knows, so why is it unjust to deprive you of the right to speak? Quite a few comrades always keep their eyes shut and talk nonsense, and for a Communist that is disgraceful. How can a Communist keep his eyes shut and talk nonsense?

It won't do!

It won't do!

You must investigate!

You must not talk nonsense!

The democratic structure doesn't appear democratic

What do you mean by this?

there are countless of expats who tell horror stories.

Expats like Yeonmi Park?
