Imagine if in the good old days they'd made a Star Wars film where the villains were a monochomatic bunch, uniformly white and male, clad in crisp white armour or wearing nazi esque uniforms, expressing disgust and having to work with aliens (the "scum of the galaxy") and crushing a galaxy rich with a diverse range of lifeforms in all shapes and colours whilst a ragtag bunch of multicoloured, multi specied and mixed gender heroes with a female in charge fought back.
Leia was female but also a rich/privileged aristocratic snob and the whole Rebellion was, in the first two films, also pretty monochromatic and nearly as if not totally as speciesist as the Empire; it was, at least or especially by the third film, more tolerant and diverse but it generally seems more like two pretty-similar factions fighting for control.
