And I suppose while we're at it, we might as well delete any dialogue in the OT that might contradict the PT. For instance, virtually anything Obi-Wan says about Luke's pa, and Obi-Wan's instruction to Luke on Hoth to seek out Yoda ("the Jedi master who instructed me"), and Obi-Wan's interaction with Yoda inside Yoda's hut, and Obi's claim that Anakin "wanted you [Luke] to have this when you were old enough," and the dialogue between Luke and Leia on Endor in which Leia claims to remember her mother, and countless other bits and pieces of OT canon that just doesn't jive with established PT dogma. Right? After all, consistency is more important than quality.
Or, you know what works even better? Watching the OT while ignoring the PT entirely. Seriously, just train your mind to believe that that worthless aborion of a trilogy was never made. That way, you avoid all the incongruity that revisionism hath wrought.
