Her post about the American tendency to look down on the disabled and the fat for "not trying hard enough" is a must-read, especially this part:
The message that we cripples and fatties get, overwhelmingly, is: Your chub/limp/whatever offends those of us who are normal. It disgusts us, so you'd better make up for it by hating yourself, saying, "Yes, I am too fat; I wish I could be thin," or "Yes, I hate having a disabled, non-normative body; I wish I could be like everyone else."
