im not attacking you personally, or speaking of you in a negative way here....but you are certainly "less capable" than a sighted-hearing person. thats not to say you can't function. Im "less capable" than a professional basketball player, or an astronaut, or someone with a teaching degree.
an argument over a word, that has a fluid definition is silly at best. In a legal sense, deafness IS a disability...in my mind, the fact that i wear glasses IS a disability, the fact im short is a disability when i play basketball. see my point?
Deaf don't like deafness being called a disability because it makes them feel like they are less than a hearing person. And therein lies the problem. Its no different than napeoleon syndrome(not sure if its a real medical syndrome) where short people overcompensate for the fact they are short and try and be tough bully's.
its all about self-confidence and knowing that you are no less than anyone else, and no better for that matter, just different. The way other people see you is moot, the way you see yourself is everything. Stop looking to hearing people for reassurance.
