There's a BNF cosplayer in the Doctor Who fandom who hates on people who cosplay the same character she does. "She's too faaaaaat," etc. Disgusting. Thing is, this cosplayer is a little chunky herself....it's just so hypocritical.

My daughter is a geek girl and dips her toes in the anime fandom...I see kids getting away with bullying behavior within the group because they hesitate to call the bullies out. It's Geek Social Fallacies (http://www.plausiblydeniable.com/opinion/gsf.html) at work.
