I have to admit, I wish they left out the whole racial superiority tidbit out of the Empire mentality. For one, it didn't seem quite as clearly defined as it could have been (Hell, take it all the way if you're going that route). It honestly felt like something that was thrown in last minute to club people over the head with the idea that Empire is Evil!
In my story, as a bounty hunter (non-human), they never made any implications that I was inferior or had shown any particular disdain for me. Exception being Drommund Kaas, where one of the officers made some offhand remark, "You look like someone who belongs in a jungle, go kill these animals that's been terrorizing our planet!"
Honestly, I couldn't tell whether that was a crack about my race, or the fact that I was a bounty hunter (Non-Imperial).
