I have a friend currently researching this precise topic; she adores reading Twilight and simultaneously thinks that it is completely damaging for young women to be reading. The distinction she drew, as far as I understood it, was that (1) Twilight is a very, very alluring fantasy - one day an immortal, beautiful man falls permanently in love with you for the rest of time and (2) canon!Edward is terrifying when considered not through the lens of Bella. Things like him watching her sleep before they'd spoken properly; he's not someone you want to hold up as a good candidate for romance.
(I personally have not read it, though I've read Alicorn's fanfic and been told a reasonable amount of detail by friends.)
I've often had half-finished LW post ideas and crossed them off for a number of reasons, mostly they were too rough or undeveloped and I didn't feel expert enough. Other people might worry their post would be judged harshly, or feel overwhelmed, or worried about topicality, or they just want some community input before adding it.
So: this is a special sort of open thread. Please post your unfinished ideas and sketches for LW posts here as comments, if you would like constructive critique, assistance and checking from people with more expertise, etc. Just pile them in without worrying too much. Ideas can be as short as a single sentence or as long as a finished post. Both subject and presentation are on topic in replies. Bad ideas should be mined for whatever good can be found in them. Good ideas should be poked with challenges to make them stronger. No being nasty!
