I don’t think there’s such a thing as a “true” Star Wars fan. If you’re a fan of something then, er, you’re a fan in any sense of the word e.g. “true”, “real”, “proper” etc.
Years ago I used to take the piss out of people who liked the PT and tease them saying they weren’t “proper” SW fans but with maturity I realised that was BS. If you you like all or a part of SW, you’re a fan.
Now, about people who like the Christmas Special…
