I know I'm 3 years late on this, but Obi-Wan and Anakin's conversation at the end of ROTS makes absolutely no sense.
1- "Only a Sith deals in absolutes" - I shouldn't have to point out the obvious contradiction, that this statement itself is an absolute.
2- Was Obi-Wan disputing Anakin's labelling of him as an enemy? After he just told Padmé that he'd probably have to kill him?
3- If he said he wasn't his enemy because he wanted to win him back, then he just called Yoda a Sith.
4- Then again, Yoda did contradict his "A Jedi never uses the Force for attack" thing pretty flagrantly.
5- If he was trying to win him back, insulting him like that might not be the best way to win his affection.
6- "Anakin, the Chancellor is evil!" "From my point of view, the Jedi are evil!" "Well, then you are lost!"
Obi-Wan is the one dealing in absolutes! Anakin is dealing in relativism! This makes no freaking sense!
7- I'll give Lucas the benefit of the doubt and assume he only thought "if you're not with me you're against me" was a Bush quote, and he wasn't actually trying to say Jesus is a Sith.
