People from Munich REALLY celebrate that they are from Munich and from kindergarten onwards a sense of snobility is distilled into your soul.
"Helles" 0.5l+ is the only allowed beer and you have to meet a "Trachten" quota (traditional clothing). The Lederhosn has to come out at least 5x per year and dear god if it is a cheap model below 300€ which is already considered trash.
Stopped Strauss! and the likes comes to mind. Anyone from the south, no matter how quiet and timid (Stoiber/etc.) - or how brutish and hawkish (strauss) - can not be chancellor of germany- the cultivated guards of civilization forbid it.
Even if they turn out to be wrong entirely- results in support for anti-western terrorists, economic support for imperialist land-empires and having a nuke right now is what half of europe has on the shopping list. There is never a moment of reflection- the north is just that more advanced in culture.
The real reason is just the same thinly veiled racism- northern Italy has for southern Italy. Nobody in the south believes that any candidate they post, could ever make it.
Well, the thing is: 0.5L is considered to be too much today for most, lots of locations are switching to 0.33 longneck bottles (esp. the ones with younger folks, also you can price it cheaper)
Regarding trachten quote: Do you have a link here?
The only thing that really helped to covercome these century old - was ironically the Conscription for the Bundeswehr in the cold war, intentionally mixing recruits allover germany and binding groups of friends together. That is now absent for a while- but the Ruhrpott and hamburg have missmanaged germany for quite a while now - and it shows, as subtle cracks of doubt in the superiority surface.
Cumex and Wirecard showed that elite as the lame ducks without a plan they really are.
PS: This explicitly ignores the Neo-prussians of berlin and the insults they throw at everything outside in the "incest-villages" as they call the rest of germany.
