Straight up said that it’s commonplace for North Koreans as a whole to understand it to be a dictatorship

Yeah, they call it a dictatorship of the proletariat. It's a Marxist concept. They are Marxist.

Juche Gang was white people nonsense

If I'm thinking of the same post as you, they said that North Koreans have a difficult time understanding how a gang could be seen as something positive. It's absolutely because they don't have hip hop culture over there. I don't think that makes it bad to say "Juche gang", because we say it to other Western comrades who understand the intention behind the phrase.
