i feel elitist about fic a lot, because i have so so many pet peeves related to writing. this is why i mostly keep the ranting in chat and out of my journal - to stay as far from wankishness as possible. but rest assured you're not alone! there are zillions of (usually quiet) grammar freaks out there, privately frothing at the mouth over the same things you are. i think there are more than a few communities devoted to it actually, although i don't belong to any. :)
