Okay so where to I start... You can ask any Bundesliga fan to share a few words about the RB Leipzig football club and you will get these same words as a response: “Nein zu RB,” meaning No to RB.
Almost all of Germany has a dislike for RB Leipzig, but what is the reason?
Just two words: RED BULL.
In Germany members own football clubs, not businesses. But RB seem to be the exception to that rule, and many people dislike that.
All fans from all clubs want to keep it that way, they way to keep the tradition.
The German FA seems to have turned a blind eye to RB Leipzig, perhaps in part because the company is investing so heavily in the old East Germany where big football clubs are so scarce. Leipzig alone have somewhere betwee 480-500,000 people but no big football club to follow.
In Germany there is a 50+1 rule, designed to prevent investors from gaining majority rights in a club registered as a stock company. Yet Bayern can have corporations buy 10% a piece in shares, divide stocks, and claim they are obeying 50+1 while takng no less money than RB puts into Leipzig.? Hypocrisy somewhat.
Leverkusen are owned by Bayer and VFL Wolfsburg are owned by Volkswagen.
Dietmar Hopp who is worth 6 billion has been investing heavily in Hoffenheim since early 2000's and has moved from from the lowest division in football to the Bundesliga.
Union Berlin, Erzgebirge Aue, and 1860 Munich (all tradition-laden clubs) refused to play friendlies against RB Leipzig two summers ago. That's how passionate they are.
So yeah, the hate is real and it's strong and it won't go away.
