Here's some of the reasons that I hate the Sith:
- makes Palpatine somebody who does bad things "because he's a Sith" instead of somebody who does things because of his own ambitions
- Takes away Palpatine's uniqueness
- An organization devoted to being selfish makes no sense.
- the EU acts like they're neccesary for the universe to exist. The idea that anything is neccesary for the universe to exist is beyond absurd.
