Its a shame that its almost OK for people to insult slim girls for looking unattractive, esp since it always seems like a backlash from people trying to loose weight. It works both ways. Both gaining and loosing weight is very very difficult. Neither being fat or thin is 'correct'.
I've successfully gained a bit of weight recently, but I am still very aware of how skinny I am in comparison to other people.
What an ass, seriously though men who think that every woman should cater for his individual tastes are plain selfish.
