The problem I have with those thigh gap inspirational pictures is not that the women are so thin, it's that it's a way to encourage women to learn how to be anorexic. I attempted to be as anorexic as I could when I was a 16-year-old back in ancient history before the personal computer. It messed me up for the rest of my life.
If I had been encouraged in more positive ways, perhaps if I had had PE classes that weren't Lord of the Rings disasters and that taught fitness Primal-style, I might have had a different experience in the years that followed. Instead, I was left to fend for myself, to count calories obsessively over and over in my head all day long, counting, recounting, trying to numb myself from the hunger and discontent. A horrible thing to do to try to be accepted.
