That is something you have no shortage of Go-Mer. You're constantly telling us "I don't think he meant it that way". If that's the case, he needs to tell us what he meant and not keep telling us something else.
I think a lot of this comes from the old video "From Star Wars to Jedi", but I'm not entirely sure about that. Some others around here with better memories than mine could probably tell you exactly what places he said it. I don't have the time or inclination to search the web or look through my old videos to find the exact quote, but I know I've heard it.
He also completely contradicts one of his own story elements in the prequel commentaries. In the commentary of AOTC, he clearly says "the dark side is stronger...at least in the short term". Yes, I could hear it coming as I watched the movies. Yes, it disturbs me that he said it. It almost invalidates what Yoda tells Luke in ESB "Is the dark side stronger?" "No, quicker, easier, more seductive". Thanks George. The lively debates I had with friends about which side was stronger came to an end at that point. There's no point trying to have a debate like that based on what Yoda says when you have the creator telling you otherwise. Again I say thanks George. This is minor, but it really pissed me off when I heard it. But this is way OT.
