I totally understand that you really like Big Bang, but I think there should be no distinction between fan and, as you say, huge fan. Why are we fans in the first place? Because they made their names known as ARTISTS. They became celebrities and you became a fan because they're singers/artists. You can love someone unconditionally if you personally know them, but in this situation, we're all equal as fans. Fans are entitled to criticize BB's music (in a constructive way, of course) if they don't like it. It doesn't make someone less of a fan if they do that, in my opinion. In fact, it's better because this lets BB know what fans like and they can improve their music. Even if you don't like the music, you can still support them, yes, but you're also entitled to say "I don't like it". That doesn't mean you're not a "huge fan". This is what I think.
