It is confusing for those outside the community. A person who had full use of her legs but severely limited use of her arms and hands would not be considered "paraplegic". However, if she had no use of her legs, the same condition of her arms would classify her as "quad" rather than "para".

Yes, it would be nice if we were all inherently sensitive to this nuance. That isn't the case, so I appreciate that your comment actually attempted to inform rather than simply castigating like sibling comments.
