The cultural construction of disability, is a big part of why we talk about it I think. The reason why its not as addressed as topics like race, ethnicity, or gender is because we can't relate. A person who is walking could never understand just what a person has to go thru on a daily basis or what i mentally challenged person is thinking. For example on t.v. its not addressed because people watch shows in which they can relate and will not watching something they don't know or understand, this causes people to ignore and be ignorant to the situation.
