To me an immigrant isn’t necessarily a settler, unless they displace the current inhabitants, or they want to replace their systems of governance / impose their own worldview on a people who have no interest in it. Vietnamese people had no use for petite-bourgeois anarcho-communism in the past, and have no use for it today. He’s probably not as bad as someone calling for regime change or an overthrow of the CPV, but he should leave his petit-bourgeois ideology and the door and learn about why the vietnamese people chose and continue to choose marxism-leninism.
