Knowing every little detail about the members of a band and their families is not "dedicated."
That is obsessive.
Dedicated does not mean you will
insult and attack anyone who doesn't like them.
That is also obsessive.
Dedicated means that, no matter what,
you will always love and support the band and anything the members of the band choose to do.
It means that no matter what anyone else says, your love for them will stay the same.
It means you will never forget what they have done for you just by existing.
People seem to have forgotten
that there is a difference between the two.
