All fans are real fans
There is no such thing as a true or fake fan.
If you like the Original trilogy, Prequel trilogy, Sequel trilogy, KOTOR, any of the animated series, Legends, new canon, and yes even Jar Jar. Doesn't matter, being a fan of any part of Star Wars fan is still a fan of Star Wars.
Any fan that says otherwise is just wrong, Star Wars has a large collection of media that each composes a part of it. Certain parts resonate with people more than others, we can all like different things.
We are all fans.
Except the holiday special.

Little known fact: You can like the Prequel Trilogy and the Original Trilogy at the same time
