Similar to England's culture then.
I mean England is equally big on "support your local team" type of stuff. But other than that nah, way different.
England is still a corporate fuckfest, ultra culture isn't a thing, you are not allowed to stand in the stadium and season tickets cost 10 times what they cost in Germany. Germany's fan scene is very involved in political shit regarding the clubs, constantly organizing protests or boycotts even when the Bratwurst-price is raised by 50ct. They put up a resistance against DFL or the clubs whenever they act "out of order", and thus create kind of a balance between club and fan interests that keeps things as they are.
This level of involvement is not present in England. If a club owner wants to further raise ticket pricing to exclude even the last bit of working class from the stadiums then reactions in England would just be outraged Twitter posts, but that's it. Nothing that would actively change anything.
Newcastle was almost taken over by some incredibly shady Saudi blood prince, and majority of their fans actually cheered for all the money being pumped in.
This would be unthinkable of a German club and it's supporters. It's essentially a Red flag, despite the success that it could bring.
Important to note that this however doesn't mean German fans just resign to imcompetetive superiority. Many fans DO want change. But not regarding 50+1.
Almost everyone is on board with salary/fee/agent caps etc. People want to bring the big clubs down, rather than the small clubs up.
