I haven't read Twilight, and I don't criticize books I haven't read, but I do object in general to the idea that something can't be ideologically offensive just because it's justified in-story.
Birth of a Nation, for example, depicts the founding of the Ku Klux Klan as a heroic response to a bestial, aggressive black militia that's been terrorizing the countryside. In the presence of a bestial, aggressive black militia, forming the KKK isn't really a racist thing to do. But the movie is still racist as all hell for contriving a situation where forming the KKK makes sense.
Similarly, I'd view a thriller about an evil international conspiracy of Jewish bankers with profound suspicion.
I think it's relevant here that vampires are not real.
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!
