The restrictions for leaving and entering have not been imposed on them externally, this attitude of Korea predates even the Roman empire” =/= “we know they don’t let people in because they’re isolationist”.
You’re saying the same thing twice there. The fact you say it isn’t, doesn’t mean anything when the actual statements are functionally the same. No matter what they both place this issue at the feet of the Koreans, which is what the disagreement was about.
They’re isolationist because it’s a cultural value derived from their location relative to their neighbor
So you are saying they are isolationist. Super. ut that has already been argued with you and instead you moved the goalposts to be about proving you said something you thought you didn’t say, which you are now once again saying
I’ve hyperlinked to a few sources. I can hyperlink to more as well.
As we have already gone thru, you’ve hyperlinked to two things. Do you not understand how references work? Do you need everything explained twice? Yes please provide your sources for god’s sake this is the third time I’m telling you how sources work.
Are we basing validity of sources based on fame? How many others agree with it?
You do - you rely on the reputation of your alleged sources by way of them being large established brands. I think this is a silly way of evaluating the validity of a sources claims, but it seems to be your primary requirement.
How many narrative holes their messages have? How old the sources are? Their nationalities? Whether they’re blocked where you live?
Yes this is called being critical of your sources. It’s an inherent part of any dissemination of information - not to just blindly accept statements presented by others. All of the things you mention help evaluate wether the source might have a bias, though the really big thing is cross-referencing claims. Interests of conflict and bias are helpful when conflicting narratives occur.
Do you not get the point of references? Why do you think we are taught from an early age to engage sources with skepticism?
