You completely ignored my second, and more important, point. Absolutism and relativism are about completely separate issues. Obi-wan is clearly no absolutist, but he's not a relativist either. He thinks lying and deception can be perfectly ok and indeed even the right thing to do. He lied to Luke about Anakin's relation to Darth Vader, at least if you take his words literally. That doesn't mean he's a relativist. He did it because he thought it was right to do it in those circumstances, and it would have been right for anyone to do it in those circumstances.

Relativism is about right and wrong varying from person to person. A more radical relativism is about truth and reality varying from person to person. The Sith seem to want to rely on relativism (even if Palpatine doesn't himself really believe it, as far as I can tell, anyway). They also will treat things as absolutes when it suits them. It may be that Palpatine endorses neither but uses what will help him achieve his ends.

But Obi-wan is clearly no relativist if he thinks the Sith are just plain evil. He isn't an absolutist, because he thinks there are complicating factors that make it harder to determine the right choice, and when he finally has to choose what to do he thinks deception is actually right in that particular case because the circumstances make it so. That's a denial of absolutism. It's not relativism.

As for the motivations of Lucas, you're treating me as if I made a more substantive claim than I did. I didn't say he didn't let the language of Bush shape his language here. I said we can't assume that, and we know the plot isn't about Bush because it existed before him. We also know that if it were going to be about Bush it would have involved something much less severe. Bush didn't put Saddam Hussein in power in order to help himself become president. He didn't get Saddam Hussein to start a war so we could have enemies to unite us in war. He didn't coordinate some massive conspiracy by playing both sides.

At most Lucas could have been saying that Bush in some of his mannerisms and language is in some very small ways like Darth Sidious in his mannerisms and language, and even if that was the point then he must have realized that he would be making it about Jesus and Christianity as well. I don't think he's that stupid. That's why I think he may have been hinting that thinking in terms of exclusivity might eventually lead to danger if you don't watch it, because people who do evil do that. He may have badly misinterpreted Bush and thought of him as an example of that. He couldn't have been saying that all who say things like that are evil, not unless he's completely stupid, and I like to give people the benefit of the doubt on things like that.

That's not how people are portraying what Lucas has tried to do in this film, politically speaking.
 

Sorry. That last sentence was written after the first sentence of the previous paragraph, and I didn't notice that all the stuff in between made it make little sense in its current context.
 

By the way, the link to my post has changed. It's now here.
