No. It is just a lack of intelligence of those who believe it. But usually one learns that once it gets obvious the self proclaimed greatness has no bases in reality.
Discussion
i don't actually understand if you're referring to Bavarian topic or is it just a general discussion😂
Generally I question that there is value in evaluating the own successes higher than others to legitimate power over others. When patriotism is not used for legitimating some power over others then it is might not harmfull, but I would still rate it as useless.
So general discussion directly answering to the head note.
