I sort of feel like despite the uproar some sections of fandom would happily sacrifice all the dark fic writers to keep themselves safe.

No, because they wouldn't necessarily be that safe -- when a wave of moral panic strikes, it's important to try to stop it in the first ditch rather than the last before it builds up a head of steam. (Wasn't that a splendid mixed metaphor, eh?) On the other hand, I think it's useful for fans of this stuff to stop and take a good look at how far off-centre it actually is for most people -- if for no other reason than that there's a better chance of formulating a successful response then.
