I've heard a lot of things about the USSR. But not once did I hear someone actually say they were ethno-nationalist. The USSR, compromised of multiple countries and ethnicities, known for world wide aid to SA countries, Asian countries.
North Korea certainly isn't a paradise but it's doing what it can and they are making process, despite being sanctioned off the Earth. If a country giving a Middle finger to the west doesn't get your (critical) support, don't be a leftist then.
Ah yes, USSR were national and ethnic minorities were given effective affirmative action programs and white supremacists who violently reacted were quelled with no mercy. USSR where African Americans immigrated to and said they finally were treated like a human being for the first time in their lives.
Literally just making shit that is the complete opposite of reality but go off little man.
