“I like the prequels.” That’s absolutely fine. You can like whatever you want. Your opinion is 100% valid. You are a real fan.
“I don’t like the prequels.” Also absolutely fine. Nobody said you have to like them. Your opinion is 100% valid. You are a real fan.
“The prequels ruined Star Wars forever and anyone who likes them is a moron.” Take your head out of your fucking arse.
