Shouldn’t have said illegality because it is not illegal, but it does lower your status.
Like, whatever, if you want to believe the DPRK is some classless paradise alright, I can’t really change people’s minds here and I’m not that interested in doing it either, but I suggest you find some decent documentaries which show what life is like in the DPRK and talk to North Koreans inside Korea. I’m not talking about the commentary of the presenters or whatever, I am talking about what the people actually talk about and consider normal.
But I am talking about being liable to persecution because of your status. Being designated as hostile to the party is absolutely destructive.
