Evidence?

You presented nothing besides pointing to the North Korean constitution and believing what is written there. You also believe that the D in DPRK actually means they are democratic, and that somehow power passing from father to son without any election is normal and acceptable. Except if countries without a communist aesthetic do it, then it's a monarchy.

Just admit it, you are an American Gen Z LARPing as a revolutionary. It's easy to talk when you never had to live in a 3rd world country under an authoritarian ruler.
