You aren't bulimic just because you threw up once, you aren't anorexic just because you skip lunch. Fats always claim to be anorexic just for going two hours without snacking. But I also think most of the disdain for "eating disorders" is that bullshit false sympathy, facetious moral superiority, and patronizing, self-serving concern.  Tmbltards are dumb as shit, but I think the one thing they are right on is the concept of "concern trolling". Like who really gives a shit?
