Eating disorders: Coming soon to a disabled person near you?

Okay, so today I feel less Rah Rahish, but there is something I'd like to tackle. I just read a blog by a gimp (her word, not mine, so used with tacit permission) who was discussing her new need for attendant care quite well. In response, one poster said that she (the blogger) should use crutches (which she does) if possible and that the use of a wheelchair decreases life expectancy and something about how wheelchair use is "easier" than bipedal locomotion. While I didn't consider this poster to be snippy and she seemed genuinely concerned, this comment still bothered me and I said so.
One reason was because it assumed such advice was wanted,needed, and not heard before (and folks, never assume people with disabilities have not heard this kind of thing before) which feeds right into the idea that most disabled adults need guidance from people without disabilities. This is a common, painful, frustrating assumption for many of us with disabilities. But the deeper reason I was affected was because these kind of comments, combined with the social denigration of disabled people, can lead a person with a disability to develop anorexia, bulimia, and compulsive exercise disorders because we know we do not "measure up." As a researcher, I have heard many stories of this and in one project I did, 4 out of 10 of my research participants said they were currently struggling with one or more of those and all 10 said they had skipped meals in an attempt to lose weight. This saddens me. So the next time you hear (or want to say) a comment that talks about how disabled people need to move more or that wheelchair use is "easier," think about the impact it may be having. We disabled people often already have poor body image. Please don't add to it. If we all celebrate ALL sizes, shapes, and ability levels without assumptions, we will all be better off.
