Fatphobic Bigot!
Over on LJ the fatshionista community is dedicated to, well if you couldn't tell fat fashion. There's some disagreement about the merits of a couple of items in a couple recent posts, but on the whole, not wanky.
Until a thin girl shows up. Some wonder what she's doing there, and accusations of fatphobia, bigotry, basic lack of logic, and inability to understand complex comments, they are a-slung. Then, the irate thin girl leaves with the parting shot: And from now on, I'm not even going to feel *sorry* for you!
As a direct result of this wankery herself_nyc has created a new community of her very own: fatshion_victim. The fatshionistas, they are not happy.

Fairly small, but diverting.

ETA: The fatshionista mod weighs in.
ETA2: Cause ruuger pointed out I didn't explain what they're even fighting about (oops...): The argument is over a black velvet skirt and a)whether or not it'll make the wearer look short and fat b)whether or not that's a bad thing and c)that's not what they OP asked, shutup you fatphobic jerks. herself_nyc kind of started it, in that hers is the first post in the thread, but the thin girl causing all the ruckus is temp_f.
