The thread title is misleading
The "vague history" terminology handwringing is asinine
Call it what you want. It's fiction, it's not a governmental bureaucracy. If the phrase "vague history" makes you crap in your pants and squish it twixt your buttcheeks, then DON'T USE IT. If you want to discount the following sequels, you can. It's up to you. it's FICTION
NONE OF THIS ACTUALLY HAPPENED. IT'S TOTALLY FICTIONAL
If you wish to disregard III and IV--YOU CAN DO THAT. There's nothing that says whatever "canon" is has to have ANYTHING to do with how YOU enjoy the movie.
To then get so wrapped up in TERMINOLOGY to the point where you start diarrhetically spraying all over damn near every thread about how people are using words you don't like? That's some petulant petty bulls**t. You can't make people not use words you don't like. You can get a sense of perspective and common sense, or you can stamp your feet like a spoiled 4 year old that can't change the rules of the game he's playing.
And again, this whole thread is a misrepresentation of what was ACTUALLY said in the interview, as was pointed out by the few posters here who actually READ the article. At least change the thread title, somebody, so they don't wander in getting the wrong idea and smearing this crap all over the forums
