saying that skinny models or stars are the reason that young girls develop anorexia, bulimia, etc. is just like saying that plus size models or stars are the reason that young girls develop binge eating disorders. it's great that everyone is advocating for healthier "role models" for teenage girls, but why is it suddenly a terrible thing to be thin? it isn't fair to accuse a thin person for causing eating disorders - which, just for the record, count as mental illnesses.
just like being too thin is unhealthy, so is being overweight.
