well, even those who hate the prequels and love the OT are still fans.
if you love something, you are a fan. what if GL gets senile and pinches a big loaf, sticks a lightsaber on it and calls it a jedi, then decides to film it and call it "episode7-return of the fecal matter"
now, if we dont like it we are not real fans? thats hogwash.
btw, i know i make an EXTREEEEEEEEEME example. i do love the prequels.
