Few fans of science fiction do not remember the moment in Star Wars when Luke Skywalker enters the cantina at Mos Eisley, accompanied by C3PO and R2D2 and is told “We don’t serve their kind.” Luke is confused, and the barman explains that ‘droids are not wanted in his establishment. So the ‘droids glumly go to wait outside while Luke and Obi Wan meet Han Solo.
Nothing else happens related to this incident. The hateful behavior of the barman is not addressed. We’re left to assume, I suppose, that someone is always at the bottom rung of the social ladder, and such people are always discriminated against. In the Star Wars universe, those disenfranchised people are ‘droids. The moment stands that hate is a fact of life.
