Actually, this is why you fail.
Y'see, even if you tout absolute fan purity as believing ONLY in movie-canon, you STILL have to attempt to explain all of the idiosyncracies in THAT. How is it Leia can "remember" anything about her mother's personality when it's made very clear in Episode III that she only sees her alive for a few seconds as a newborn? Why does Obi-Wan tell Luke that Yoda trained him when Episode I shows instead that it was Qui-Gon who was his immediate Master? And so on, and so forth. (Note: PLEASE don't respond trying to offer up "explanations" or have "friendly discussions" about any of the aforementioned points or others that have/will undoubtedly crop[ped] up in SW fandom. PLEASE, don't, or it will send Anakin into a fiery rage and incite him to brutally slaughter a roomful of innocent you- oh, wait. Whoops. BUT PLEASE, FOR THE LOVE OF ALL THAT IS HOLY OR PURE AND/OR WHATEVER WILL CONVINCE YOU NOT TO BE A DOUCHE BAG, DON'T. PLEASE AND THANK YOU.)
The fact of the matter is, an empire/fanbase as long-running and successful as SW is bound to have a few snits along the way - it's to be expected. And in fact, a lot of fans will agree that its idiosyncracies are what makes it so charming. (Somebody try telling that to George "I edit all my movies and the original Original Trilogy will NEVER SEE THE LIGHT OF DAY ON DVD BWAHAHAHAHA" Lucas, though.) One can still be a fan of said movies whilst enjoying pockets of the Extended Universe - even if said EU pocket doesn't quite match up with movie-canon. Because hey, movie-canon doesn't quite match up with movie-canon.
So in the end, it doesn't really matter quite as much which branch of the universe you pluck from. They all have their good and bad points; and from my experience and (infinite, to be sure) wisdom in such matters, being holier-than-thou about one sliver of it is only going to make you eat your words somewhere down the line. Maybe not today, maybe not tomorrow, but rest assured, my darling nerfherders - that is what fandom is all about.
In conclusion: may the Force be all-encompassing enough for all canon so everyone will just shut the fuck about it already.
