Yeah... I went to my friend's house last week and I got death stares from her fit son's chubby girlfriend (when she would actually make eye contact with me) despite not paying any particular attention to him versus anyone else. On a regular basis I have to put in extra effort to be nice to fatter girls if I have to work with them or something, just so they don't automatically hate me. It's pretty fucking annoying and feels fake, but I'm not in a position in life to be able to say what I really want, so it's the best method I've found for now.
