First of all, it's 'which', not 'witch'. Second, you have no right to tell if a BVB fan is a real one or not. It's a lot harder to go to one of their shows from here, Romania. A real fan must understand the meaning of the music. I'm not supposed to know every detail about them. I know the basics and I'm fine with this.
P.S.: Your grammar kills. And I tell you this, me being a romanian.
