Well I don't think you have the right to decide who is a fan and who isn't. Okay, what about this? When I was younger, I loved Slipknot. I was 6, and my parents hated them. So they decided to only allow me to listen to one song (Wait and Bleed). I Soon learned every last word of the entire song. I would listen to the song day and night, and even tell random "grown-ups" to listen to them. I believe that since you are ridiculing people you don't even know, that makes you the poser. Being a true fan is not listening to all of the songs, it is understanding and enjoying the songs you listen to.
