I think it would probably not be best to remove the propaganda posts in question, but would probably be good to perhaps have warnings applied to posts linking readers to authoritative sources of information about the subject, so the readers can make their own unbiased judgments.
Freedom, or no freedom? There's no grey area here. Should people be able to say what they want on this forum, or should all posts be reviewed against QS's definition of propaganda? Who gets to review the "Authoritative Sources" to determine whether they are valid, or if they are just spreading more propaganda? Who gets to review the reviewers for bias?
My suggestion is that you engage in calm, rational discussions, provide references that support you position, recognize that your opinions are just as biased as your opponents, and allow others the same freedom. You won't convince everyone. You may not convince anyone. Just don't take it personally.
Of course, I favor freedom.
With the kind of propaganda I am referring to, particularly the kind being published by
Ljunior, I would say the publisher (I am intentionally not using the word 'person' as I have my doubts he is writing in his personal capacity, or even if it is a single person behind the account) does not necessarily believe what is being published, and he is taking steps to make it difficult to counter his statements. For example, he is making his posts full of images, so a casual reader will not be as likely to read the post immidiately after his post. This makes it difficult to counter what he is saying.
The authoritative sources should be chosen by someone who is responsible for the reputation of the forum. If authoritative sources are chosen that are not reliable, or are too biased, the forum's reputation will suffer. I don't think the forum should say that anyone is right or wrong, or that the linked authoritative sources are right or wrong, but I do think some of these posts should contain links to additional information so readers can decide for themselves.
There is a distinction between someone like Ljunior, and someone like
jrrsparkles, who very well may believe what he is posting, and IMO is repeating what someone in his family, or friend group taught him. jrrsparkles is not doing anything to impede discussion, while Ljunior is via his very long posts.
We don't allow people to post about bcash in the bitcoin subs, claiming that bcash is bitcoin. We also don't allow inauthentic behavior that might artificially increase their threads or posts visibility.
