Anti-Alien Empire: Star Wars Rethink video

Interesting I feel the Empire's fall was due to more than its general dislike of aliens. I believe it was due to the fact that they oppressed everyone they came across, certain human groups included. However, Star Wars Rebels and the game Star Wars Rebellion shows the Empire makes use of aliens for their own purpose. In Star Wars Rebellion various Imperial Spies were aliens, in Star Wars Rebels the Inquisitors are all aliens. I think the Empire generally has a distaste for aliens however I don't believe they simply hate them I think the Empire and the humans loyal to the Empire see them as servants to the greater race of the Galaxy. Hence why so many alien species are forced into slavery by the Empire. The Wookiee's and Genosians, for example, were used as slaves to build weapons for the Empire. Even still the Empire has no problem with wiping out entire species as they showed that in Star Wars Rebels where the Empire essentially declares exterminatus on Geonosis. By releasing biological weapons on the bugs.
