Yeah, I totally agree, I've always been skinny and in the past have been called things like a stick or told 'you're all skin and bone', and while I wasn't too upset at these comments as I'm only slightly insecure about my appearance, it still really annoyed me that if I had said the equivalent to them like calling them a whale or 'you're all blubber' or something similarly harsh, I would have been heavily criticised and shouted at for it, and rightly so. Neither should be acceptable imo, skinny people can be insecure about their weight too, yet no-one considers that.
