Yeah, I don't really get it either. Thanks for the responses by the way, but as I see it people with eating disorder should at least slightly realize what to expect at a gym. Weight scales being one of them. If you don't like seeing your weight on a scale then don't use one until you have built up some confidence. Moreover, I don't believe that people should be going there to begin with if they're that unstable. I'm going through school for neuropsychology, and if a person can't handle looking at a weight scale then they should really consider seeing a psychiatrist.
I realize that mental illnesses, including eating disorders are serious. However, individuals with conditions like that should not negatively affect an entire community in the way it is here. There are other ways to go about it that will be much more helpful for those affected by the disorder, and the others surrounding them.
