Part of the problem here is that within the horrifying statistic of 40% obese +32% overweight statistic is the way people self segregate. These Twitter hams exclusively socialize with smallfats, fats, and deathfats. They only see the area of lard all around them and all the athletes and fit celebrities on TV.  Thus they have no conception of an ordinary person who looks after themself, and refuse to believe that these people exist or that a couple of generations ago that was the majority. Their identity is based on maintaining this delusion.
